Make Smart Search library-aware (Emby dedup + TV gap-fill)

New controller/library.js queries Emby by TMDB provider id (resilient: an
unreachable Emby degrades to "unknown" so search still works).

Movies — quality-aware dedup:
- findReleases checks movieInLibrary(tmdbId) and flags each option alreadyOwned
  when its resolution is <= what you already own, so only genuine upgrades are
  offered; the release picker greys owned qualities and shows a library banner.

TV — library-driven "fill the gaps":
- GET /__api/search/seasons compares Emby's episode inventory against TMDB's
  per-season episode counts to mark each season complete/partial/missing.
- POST /__api/search/fill picks the best complete-season pack (LLM) for every
  missing/incomplete season and queues them. Front-end routes TV titles to a
  season plan + "Fill all gaps" instead of the movie release list.

Adds tmdb.tmdbSeasons; shared tmdb module import in search.js.
