The deep scan stores tmdb_id/tvdb_id/imdb_id from Plex/Jellyfin, but the workers
only ever searched by title+year and ignored those ids — re-deriving matches the
server already had exact (wasteful, and a title search can mis-match).
enrichment_next now surfaces the row's known provider id; the worker forwards it
and the TMDB/TVDB clients fetch details BY ID (one call, no /search) when it's
present, falling back to title/year search only for items the server couldn't
identify. Still grabs the overview/backdrop the scan doesn't capture.
Each video connection item (TMDB/TVDB) now has a Test button that behaves like
music's: saves the key, hits POST /api/video/enrichment/<svc>/test, and toasts
the result via the shared showToast — isolated (own endpoint, own data-attr
handler, reuses the .test-button CSS).
- Client .test() pings TMDB /configuration and TVDB /login to verify the key.
- Endpoint returns {success,message,error}; unknown service -> 404.
94 tests green; music untouched.
