- New `lists` service fetches Sonarr/Radarr library via their REST APIs
and auto-imports matching titles from TMDB into the user's watchlist
- `app/api/lists/[token]/route.ts` webhook endpoint triggers a list sync
- Unified `IntegrationCard` component replaces `WebhookCard`, handling
both webhook-style (Plex/Jellyfin/Emby) and list-style (Sonarr/Radarr)
integrations with per-type config forms
- Schema migration adds `sonarr` and `radarr` to the integration type
enum and a `listConnections` table for list-based integrations
- 212 tests added for the lists service covering import, deduplication,
and error handling
