Four coupled changes to the services-as-hub IA:
1. Nav entries use service TYPE names (Jellyfin, SSH Tasks, Alertmanager,
Grafana, Prometheus, Backups, Authentik) instead of conceptual names
(Media, Files, Actions, Alerts, Users). ssh_tasks collapses to one
entry ('SSH Tasks') instead of two. The content tabs inside each
service page surface the concepts (Files, Actions).
2. Service page gains a two-level tab structure when multiple enabled
instances of the same type exist: instance tabs on top ([Main Jellyfin]
[Backup Jellyfin]), content tabs below ([Overview] [Media] [Requests]
[Widgets]). Clicking an instance tab navigates to the sibling's route.
Single instance: no instance tabs. Replaces the dropdown switcher.
3. Config tab (connection fields, secrets, enable/disable, delete) moves
from the service page to Settings > Services tab. The service page
becomes a PURE operational view (Overview + content tabs + Widgets) --
no save/delete/config state. Settings gains a 4th tab 'Services' with
ServiceConfigEditor per instance (schema-driven config fields, secrets
with leave-blank-to-keep semantics, ConfirmDialog on delete).
4. Overview tab is now a configurable widget grid per service instance.
Each instance manages its own set of widgets on its Overview. Backend
widget list endpoints gain ?service_id= and ?scope= (dashboard|service)
filter params; the main Dashboard uses scope=dashboard to exclude
service-scoped widgets. The OverviewTab reuses WidgetInstanceCard +
WidgetConfigDialog. Empty state CTA for instances with no widgets.
All service-tab stubs are replaced; stubs.tsx deleted.
272 backend tests pass (+1 widget filter); 121 frontend tests pass (+3
instance-tabs + OverviewTab); lint/build green both sides.
PR 2 of 4 for the runtime service registry change.
- dashboard_widgets gains service_id + widget_kind columns (legacy
addon_id/widget_type kept but unused).
- Source adapters take (service: ServiceRecord | None, widget_kind, config).
SERVICE_ADAPTERS keyed by service_type; BUILTIN_ADAPTERS for backups/static.
- Backups and static stay as service-less built-ins (service_id nullable),
exposed via GET /api/widgets/builtin.
- SSH task adapter resolves the task + instance, runs over SSH, and appends a
service_task_runs history row on success/failure/timeout/error.
- Retire widgets/registry.py; widget metadata now comes from the integrations
registry + widgets/builtin. Remove /api/widgets/types and /api/widgets/sources.
- Stop default widget seeding (fresh install = empty dashboard).
- Rewrite widget tests around the service-bound + built-in model (26 tests).
Backend-only breaking change; frontend is reconciled in Slice 3. Build/lint
stay green; pytest 222 passed.
