chore: remove dead machine-level Jellyfin/Jellyseerr fields

Follow-up #1 to the service-registry change. Jellyfin/Jellyseerr now resolve
from the service registry, so the machine-level app fields are dead config.

- dependencies.py: drop dead _jellyseerr_client_for; simplify _resolve_machine
  to SSH-only.
- settings_store.py + routers/settings.py: remove jellyfin_*/jellyseerr_* from
  machine default config, get_machine_config, normalization, row mappers, and
  MachineInput.
- frontend types + Settings.tsx: drop the fields and the Jellyfin/Jellyseerr
  form sections + service options.
- Update frontend test fixtures.

Existing DB rows may still carry these keys in config_json; they are inert and
drop on the next machine save. Verification: backend ruff clean, pytest 222;
frontend lint 0 errors, build success, 70 tests.

 - 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

+## Follow-up #1 — remove dead machine Jellyfin/Jellyseerr fields
+
+With Jellyfin/Jellyseerr now resolved from the service registry, the machine-level
+Jellyfin/Jellyseerr fields are dead config. Removed from `dependencies.py` (dead
+`_jellyseerr_client_for`; `_resolve_machine` simplified to SSH-only),
+`services/settings_store.py`, `routers/settings.py` (`MachineInput`), frontend
+types, the `Settings.tsx` form, and frontend test fixtures. Existing DB rows may
+still carry these keys in `config_json`; they are inert and get dropped on the
+next machine save. No data migration required.

 - Remove machine app fields from `settings_store.py` + `routers/settings.py`
   once the UI no longer writes them.
 
+### Frontend half (this PR)
+
+- [x] `api/client.ts`: Jellyfin-backed calls (`fetchCounts`, `fetchLibraries`,
+      `fetchActivity`, `fetchUsers`, Media status/build/stop/force-stop, and
+      `queryMedia`) now send `jellyfin_service_id` instead of `machine_id`.
+- [x] `hooks/useDashboard.ts`, `hooks/useUsers.ts`, `hooks/useMedia.ts`: renamed
+      the selector param to `jellyfinServiceId`.
+- [x] `pages/Media.tsx` + `pages/Applications.tsx`: select a `jellyfin` service
+      instance via `useServiceInstances("jellyfin")` and persist
+      `jellyfin_service_id` in the URL.
+- [x] Dashboard (widget-based) and Users (default-instance) need no selector
+      change.
+- [x] Updated Applications + Media tests for the new hook/param.
+
+### Deferred (explicit follow-up)
+
+- Remove machine-level Jellyfin/Jellyseerr fields from `settings_store.py`,
+  `routers/settings.py`, and the Settings UI. Low urgency now that the runtime
+  reads from services; the machine fields are simply unused for Jellyfin.
+
 ### Verification (backend half)
