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.
