Add movie support to Fetch Data: local title/year guessing plus TMDB movie lookup

- renamr-core::matching: guess_movie() extracts a movie title (and release year, if
  present) from a filename using the same year/quality-token boundary heuristics real
  release names follow, as a fallback when guess_episode() finds no season/episode
  marker.
- renamr-core::web::tmdb: search_movie()/lookup_movie() mirror the TV client, reusing
  the same Sorensen-Dice title-disambiguation as lookup_episode(), narrowed further by
  TMDB's own primary_release_year filter when a year was locally guessed. Also exposed
  search_tv_best_match() and fixed a latent gap where the real Fetch Data command path
  (metadata.rs::fetch_season) bypassed the fuzzy show-name disambiguation entirely,
  doing its own raw first-result selection instead of reusing it.
- src-tauri: new guess_movie command and fetch_movie_metadata command/types
  (MovieFetchQuery/Outcome/Result), registered alongside the existing TV commands.
- Frontend: Item now tracks mediaKind ("tv"/"movie"/null); Match tries guess_episode
  then falls back to guess_movie; Fetch Data resolves TV and movie targets via their
  own commands concurrently and merges results. A single batch can mix TV and movie
  files - each only fills in the fields that apply to it. Movie fields ({movie name},
  {year}, reusing {airdate} for release date, matching FileBot's own unified binding)
  are documented in the naming-scheme field reference.
