feat(stats): add TMDB metadata for live-action dramas in the Library

Anime covers come from AniList, which has no live-action titles, so dramas
and movies showed blank cards with no description and split across season
folders. Library entries now carry a media kind plus a TMDB link, and the
cover-art fetcher falls back to TMDB when AniList has no match, accepting
only a Japanese non-animated title whose TMDB names match the parsed title
exactly. Entries that resolve to the same TMDB title merge into one card
regardless of season, and a Link to TMDB action in the detail view covers
anything the automatic match missed.

Release builds bundle a project-owned TMDB key injected from the
SUBMINER_TMDB_API_KEY secret at build time; tmdb.apiKey/apiKeyCommand
override it and are required when running from source.

 When older stats already grouped multiple seasons under one series entry, SubMiner moves parsed episodes into the season-specific entries on startup and rebuilds the affected summaries.
 
+**Live-action dramas and movies.** Anime covers come from AniList, which has no live-action titles. A title that AniList cannot match is looked up on [TMDB](/configuration#tmdb) instead (release builds bundle a key; source builds need your own): only a Japanese-language, non-animated result whose known titles match the parsed filename exactly is accepted, and it supplies the poster, synopsis, English and Japanese titles, and episode count. If nothing matches automatically, open the title and use **Link to TMDB** to search and pick it by hand. A TMDB show spans all of its seasons, so entries that resolve to the same TMDB title are merged into one card regardless of the season folder they came from, and the merged season titles are remembered so later episodes land on the same card. The **All Titles** filter above the grid narrows the Library to anime or live action, and a title's detail view shows whether it is a drama or a movie. Linking a title to AniList again turns it back into an anime entry.

 Jellyfin stream URLs are normalized to stable item links before stats titles are shown, so playback query parameters are not displayed in the dashboard.
 
 When YouTube channel metadata is available, the Library tab groups videos by creator/channel and treats each tracked video as an episode-like entry inside that channel section.
