feat(services): cleanup, services admin UI, docs

PR 4a of the runtime service registry change.

- Remove addon pages (/addons/:addonId, AddonPage, addons/*) superseded by
  service pages.
- Remove grafana_url/prometheus_url from backend config, compose, .env.example,
  and README (URLs now live on service records; VITE_ frontend deep-link vars
  retained).
- Add Services page (/services) with create/list/delete + sidebar nav, so
  services are configurable in the tool itself and service pages are reachable.
- Update docs/REQUIREMENTS.md service-registry section; add CHANGELOG.md with
  the breaking-upgrade note (MANAGE_ENCRYPTION_KEY required; grafana/prometheus
  env vars removed; default widget seeding removed).

Verification: backend ruff clean, pytest 222 passed; frontend lint 0 errors,
build success, 70 tests passed.

+# Changelog
+
+All notable changes to Manage. Breaking changes are marked with **BREAKING**.
+
+## [Unreleased]
+
+### Added — Service registry
+
+- Runtime **service registry** persisted in the backend SQLite database. External
+  services (Grafana, Prometheus, Jellyfin, Nextcloud, SSH task runner) are now
+  configured in the app instead of via environment variables.
+- Services page (`/services`) to create, list, and delete service instances.
+- Service detail pages (`/services/:serviceType/:serviceId`) to edit name/enabled
+  state, rotate secrets, and view the widgets a service provides.
+- Service definitions live as Pydantic modules in `backend/.../integrations/`,
+  each declaring its config schema, secret fields, and widget kinds.
+- Multi-instance support: multiple Grafana/Jellyfin/etc. instances per type.
+- SSH task runner service records run history in a new `service_task_runs`
+  table, shown on the runner's service page.
+
+### Changed
+
+- Dashboard widgets are now **service-bound** (reference a service instance +
+  widget kind) or **built-in** (backups, static text). The "Add widget" flow is
+  pick-service → pick-widget-kind → configure.
+- Deleting a service cascade-deletes widgets that reference it.
+
+### Security
+
+- Service secrets (API keys, tokens, passphrases) are **encrypted at rest** with
+  Fernet.
+
+### **BREAKING**
+
+- **`MANAGE_ENCRYPTION_KEY` is now required** to start the backend. Generate one
+  with:
+
+  ```bash
+  python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+  ```
+
+- The `GRAFANA_URL` and `PROMETHEUS_URL` backend environment variables were
+  removed; Grafana/Prometheus URLs now live on service records configured in the
+  UI. Re-create them on the Services page after upgrading.
+- The legacy widget/addon-pages model (`/addons/:addonId`,
+  `/api/widgets/types`, `/api/widgets/sources`) was removed in favor of the
+  service registry.
+- Default dashboard widget seeding was removed; a fresh install starts with an
+  empty dashboard. Add widgets from the dashboard's edit dialog after
+  configuring services.
+
+### Notes / follow-ups
+
+- Machine-level Jellyfin/Jellyseerr app config still powers the Media/Users/Files
+  pages. Migrating those onto the service registry is a separate follow-up change
+  (see `openspec/changes/service-registry/design.md` §12.5).

-## Configurable Dashboard Widgets
+## Service Registry and Dashboard Widgets
 
 ### Overview
 
-The dashboard is composed of persisted widget instances stored in the backend SQLite
-settings database. Each widget has a type, title, configuration, enabled flag, and
-sort order. The frontend renders enabled widgets in sort order and fetches data
-independently through the backend source adapters.
+External services (Grafana, Prometheus, Jellyfin, Nextcloud, SSH task runner) are
+configured **in the app** and persisted in the backend SQLite database. Each
+service instance holds non-secret config plus encrypted secret fields. Dashboard
+widgets are either **service-bound** (reference a service instance + a widget
+kind declared by that service) or **built-in / service-less** (backups, static
+text).
 
-### Widget types
+Service definitions live as Pydantic modules in the backend
+(`integrations/`); they declare the service config schema, secret fields, and
+the widget kinds the service provides. There is no runtime plugin loading.
 
-- **Jellyfin activity** — live sessions and idle users from a configured Jellyfin machine.
-- **Backups** — backup job summary and active alerts.
-- **Grafana link** — deep-link to a Grafana dashboard or panel (no iframe embedding).
-- **Prometheus metric** — result of a PromQL instant query.
-- **SSH task output** — output of a saved task run on a machine.
+### Services
+
+- **Grafana** — base URL + optional API key; provides a dashboard-link widget.
+- **Prometheus** — base URL + optional bearer token; provides a PromQL metric widget.
+- **Jellyfin** — base URL + API key; provides a live-activity widget.
+- **Nextcloud** — base URL + app password (no widgets yet).
+- **SSH task runner** — host/port/username + saved SSH key reference + optional
+  passphrase; provides a task-output widget. Tasks stay in the global saved-task
+  registry; every run is recorded in `service_task_runs` as history.
+
+Multiple instances per service type are supported. Services are managed from the
+**Services** page (`/services`) and each instance has a detail page at
+`/services/:serviceType/:serviceId`.
+
+### Built-in widgets
+
+- **Backups** — internal backup job summary and active alerts.
 - **Static text** — plain text or markdown note.
 
+These do not reference a service.
+
 ### Security
 
-- Widget `config` may not contain credential keys such as `password`, `token`,
-  `secret`, `api_key`, `private_key`, or `passphrase`, or values that look like
-  secrets (e.g., base64 blobs, `sk-` prefixes).
-- Widgets reuse machine-level Jellyfin/SSH credentials and environment settings for
-  Grafana/Prometheus URLs; no secrets are stored in widget configuration.
-- SSH task widgets only run tasks from the saved-task registry; arbitrary commands
-  are not accepted.
-
-### Addon pages
-
-Each non-core addon gets a dedicated page at `/addons/:addonId`:
-
-- `/addons/grafana`
-- `/addons/prometheus`
-- `/addons/ssh-tasks`
-
-Unknown addons render a "not installed" alert.
+- Service secrets (API keys, tokens, passphrases) are **encrypted at rest** with
+  Fernet using a single env-provided `MANAGE_ENCRYPTION_KEY`, which is always
+  required to start the backend.
+- Widget `config` and service `config` may not contain credential keys or
+  secret-looking values; secrets go in the dedicated secret fields only.
+- Plaintext secrets are never returned by the API; only `secrets_set` flags are
+  surfaced.
+- SSH task widgets only run tasks from the saved-task registry; arbitrary
+  commands are not accepted.
 
 ### API
 
-- `GET /api/widgets/sources` — list source types.
-- `GET /api/widgets/types` — list widget type metadata.
+- `GET /api/services/types` — service definition metadata (config schema,
+  secret fields, widget kinds).
+- `GET /api/services/instances` — list service instances (no plaintext secrets).
+- `POST /api/services/instances` — create instance.
+- `PUT /api/services/instances/{id}` — update instance.
+- `DELETE /api/services/instances/{id}` — delete instance (cascade-deletes
+  widgets referencing it).
+- `GET /api/widgets/builtin` — built-in (service-less) widget kinds.
 - `GET /api/widgets/instances` — list widget instances.
-- `POST /api/widgets/instances` — create instance.
-- `PUT /api/widgets/instances/{id}` — update instance.
-- `DELETE /api/widgets/instances/{id}` — delete instance.
+- `POST/PUT/DELETE /api/widgets/instances/{id}` — widget CRUD.
 - `GET /api/widgets/instances/{id}/data` — fetch widget data.
 
+### Breaking change
+
+Grafana/Prometheus URLs and credentials moved from environment variables into
+service records. The legacy `GRAFANA_URL` / `PROMETHEUS_URL` backend settings and
+the widget/addon-pages model were removed. `MANAGE_ENCRYPTION_KEY` is now required.
+
+> **Follow-up (not in this change):** machine-level Jellyfin/Jellyseerr app
+> config still powers the Media/Users/Files pages. Migrating those onto the
+> service registry (and removing the machine app fields) is a separate change;
+> see `openspec/changes/service-registry/design.md` §12.5.
+
 ## Decision Log
 
 - 2026-06-17: Decommissioned the legacy Manage-side system-metric scraping. Removed the backend `MonitoringPoller` (SSH-ran `df` on every machine every 5 min into a local SQLite `monitoring_machine_actions` table), the entire `services/monitoring_actions.py` module, the `/api/monitoring/poller`, `/api/monitoring/machines/{id}/actions`, and `/api/monitoring/disk` endpoints, the `monitoring_machine_actions` table (DROP on startup), the three `monitoring_poll_*` / `monitoring_action_retention_days` config knobs, and the orphaned frontend `DiskSpaceCard` + `DiskSpace` type. System metrics are now owned exclusively by Prometheus + node_exporter + Grafana. Kept the Alertmanager proxy (`/alerts`, `/alertmanager-status`, `/alertmanager-webhook`), `/prometheus-targets`, `/machines`, the `node_exporter_*` machine fields, and the on-demand `disk_usage` job template.

 # Apply Progress: Runtime Service Registry
 
 **Change:** `service-registry`
-**Apply run:** PR 1 + PR 2 + PR 3 (Slices 1–3)
+**Apply run:** PRs #7–#10 (Slices 1–4a)
 **Date:** 2026-06-19
 
-## Slice 1 — Backend service foundation (MERGED, PR #7)
+## Slices 1–3 (MERGED)
 
-Fernet secrets, closed `integrations/` registry (Pydantic config + widget-config
-for grafana/prometheus/jellyfin/nextcloud/ssh_tasks), `services` +
-`service_task_runs` tables with cascade delete, `/api/services*` CRUD,
-`MANAGE_ENCRYPTION_KEY` required at startup.
+- Slice 1 (#7): backend service foundation — encryption, integrations registry,
+  services + service_task_runs tables, `/api/services*` CRUD.
+- Slice 2 (#8): backend widget rebind — service_id + widget_kind, ServiceRecord
+  adapters, built-ins, SSH run logging, retired old widget registry.
+- Slice 3 (#9): frontend services runtime — types/API/hooks, frontend registry,
+  ServicePage, route swap, reconciled widget components + config dialog.
 
-## Slice 2 — Backend widget rebind (MERGED, PR #8)
-
-Widgets carry `service_id` + `widget_kind`; adapters take
-`fetch(service: ServiceRecord | None, widget_kind, config)`; backups + static
-stay as service-less built-ins; SSH adapter logs to `service_task_runs`; old
-`widgets/registry.py` retired; default seeding removed.
-
-## Slice 3 — Frontend services runtime (this PR)
+## Slice 4a — Cleanup + services admin UI + docs (this PR)
 
 ### Completed tasks
 
-- [x] 3.1 Service + new widget TypeScript types (`ServiceInstance`,
-      `ServiceInstanceInput`, `ServiceTypeInfo`, `ServiceWidgetKindInfo`,
-      `SecretFieldInfo`, `BuiltinWidgetKindInfo`; widget gains `service_id` +
-      `widget_kind`).
-- [x] 3.2 Services API + hooks (`api/services.ts`, `hooks/useServices.ts`).
-      Reconciled `api/widgets.ts` + `hooks/useWidgets.ts` to the new shape
-      (removed sources/types; added builtin kinds).
-- [x] 3.3 Closed frontend service registry (`integrations/registry.ts`)
-      mirroring the backend; `resolveWidget(widget, services)` maps a widget to
-      its component + refresh interval.
-- [x] 3.4 Service page at `/services/:serviceType/:serviceId` with config view,
-      empty-on-edit secret inputs + "set" badges, enable toggle, delete, and the
-      service's widget-kind list.
-- [x] 3.5 Route swap: added `/services/:serviceType/:serviceId`; addon route
-      retained for now (removed in Slice 4 cleanup).
-- [x] 3.6 Reconciled widget components to take `refreshIntervalMs` +
-      `description` props; rewrote `WidgetConfigDialog` around the
-      service → widget-kind picker (pulled 4.1 forward to keep the build whole).
-- [x] 3.7 Registry + Dashboard tests updated; new
-      `integrations/registry.test.ts`.
+- [x] Removed addon pages (`/addons/:addonId`, `AddonPage.tsx`, `addons/*`) —
+      superseded by service pages.
+- [x] Removed `grafana_url` / `prometheus_url` from `config.py`, both compose
+      files, `.env.example`, and README. (Frontend `VITE_GRAFANA_URL` /
+      `VITE_PROMETHEUS_URL` deep-link vars retained.)
+- [x] Added a **Services page** (`/services`) with create/list/delete and a nav
+      entry, so service pages are reachable and services are configurable in the
+      tool itself.
+- [x] Registered `/services` route in both route trees + sidebar nav.
+- [x] Updated `docs/REQUIREMENTS.md` (service registry section) and added
+      `CHANGELOG.md` with the breaking-upgrade note.
 
 ### Decision resolved mid-slice
 
-Secret edit UX = **empty-on-edit + "set" badge** (blank = keep existing; typing
-= replace). Applied on the ServicePage secrets card.
+"Full machine migration" was scoped into **4a (cleanup) + 4b (Jellyfin/Jellyseerr
+migration)** because removing machine-level Jellyfin/Jellyseerr fields is deeply
+coupled to the Media/Users/Files pages (load-bearing) and there is no
+`jellyseerr` service definition yet. 4a ships the safe cleanup + the services
+admin UI; 4b does the machine-app-field migration as its own reviewable change.
 
-### Files changed (Slice 3)
+### Files changed (Slice 4a)
 
-- New: `api/services.ts`, `hooks/useServices.ts`, `integrations/registry.ts`,
-  `integrations/registry.test.ts`, `pages/ServicePage.tsx`.
-- Modified: `types/index.ts`, `api/widgets.ts`, `hooks/useWidgets.ts`,
-  `components/WidgetInstance.tsx`, `components/WidgetConfigDialog.tsx`,
-  `pages/Dashboard.tsx`, `pages/__tests__/Dashboard.test.tsx`, `App.tsx`,
-  all six `widgets/*.tsx` components, `widgets/index.ts`.
-- Deleted: `widgets/registry.ts`, `widgets/registry.test.ts`.
+- Backend: `config.py` (removed grafana_url/prometheus_url).
+- Compose/env/docs: `docker-compose.yml`, `docker-compose.dev.yml`,
+  `.env.example`, `README.md`, `docs/REQUIREMENTS.md`, `CHANGELOG.md` (new).
+- Frontend: new `pages/ServicesPage.tsx`; `App.tsx` (routes + nav); removed
+  `pages/AddonPage.tsx`, `addons/*`.

-### Deviations / notes
-
-- `WidgetConfigDialog` was rewritten in this slice (pulled forward from task
-  4.1) because the old dialog imported the deleted widget registry and would
-  not compile. The SSH task-output widget keeps a dedicated task picker; other
-  widget configs use a generic schema-driven field editor.
-- Addon pages (`/addons/:addonId`) are kept compiling but superseded by service
-  pages; Slice 4 removes them and the now-unused machine Jellyfin/Jellyseerr
-  fields + `grafana_url`/`prometheus_url` env vars, and writes the changelog.
-
 ## Remaining work
 
-- Slice 4: remove addon pages + machine app fields, remove
-  `grafana_url`/`prometheus_url` from config + compose, docs + changelog
-  (breaking upgrade note).
+- Slice 4b: add `jellyseerr` service definition; rewire `dependencies.py`
+  Jellyfin/Jellyseerr resolution to the service registry; migrate the
+  Media/Users/Files/Dashboard selector from machine_id to service instance;
+  remove machine-level Jellyfin/Jellyseerr fields from `settings_store.py`,
+  `routers/settings.py`, and the Settings UI.
