feat: wire OIDC, image watcher, and integrations to live API endpoints

All announced features now have working REST endpoints:

OIDC / SSO:
- GET /api/auth/oidc/providers — list configured SSO providers (no auth)
- GET /api/auth/oidc/login/{id} — initiate OIDC login redirect
- GET /api/auth/oidc/callback — handle IdP callback, create session
- Role mapping from IdP claims via map_claims_to_role()

Docker Image Watcher:
- GET /api/image-watcher/config — get watcher configuration
- PUT /api/image-watcher/config — save watcher configuration
- GET /api/image-watcher/status — cached check results for all containers
- POST /api/image-watcher/check/{container} — force check a container
- Background task checks all containers on configured interval

API Integration Framework:
- GET /api/integrations/connectors — list available connector types
- GET /api/integrations — list configured instances with health
- POST /api/integrations — create new instance
- GET /api/integrations/{id} — get instance details
- DELETE /api/integrations/{id} — delete instance
- Background health check loop (60s interval)

AppState: added oidc_pending_flows, image_watcher_cache, integrations fields
Zero dead code warnings. 74 tests pass.
