fix(node): correct TMDB movie matching, per-file overrides, rematch

A batch of wrong poster-grid matches found live on a real library
(2026-08-29): a two-volume film's second part matched the first; a
numbered sequel matched a same-year making-of documentary; several
entries of one franchise matched a single early entry whose localized
TMDB title is the franchise name; one matched nothing. One mechanism:
_tmdb_search returned the first candidate query whose title-similarity
ratio merely cleared 0.6, before alternative_title / the Roman-numeral
variant was ever tried.

Matching:
- title_parse: fold guessit's volume/part number back into display_title
  so the parts of a multi-part film stay distinct in the query, the card
  and the override.
- _tmdb_search: keep a strong PASS 1 fast path (ratio >= 0.85, one
  request), otherwise score every candidate query and pick the best. A
  year-exact rescue lifts a sub-0.6 top hit to the confidence floor only
  when TMDB's own year-filtered result lands exactly on the filename's
  year. No local re-ranking of any single result list; no tmdb.py change.

Fix match / rematch:
- _admin_exec_tmdb_override: a movie override touches its own file only
  (guessit gives a whole franchise one display_title); a show override
  still fans out. Corrected files are marked in media_cache.tmdb_override.
- media_cache: tmdb_override table; clear_file_tmdb / clear_tmdb_matches
  drop auto-resolved matches while sparing manual corrections.
- ops.rematch_video + `meshbay-node video rematch` (loopback endpoint +
  CLI verb): re-resolve a group's video matches after a matcher fix.
  file_tmdb is keyed by content hash and otherwise only pruned on
  deletion, so nothing dislodged a cached match before.
- a rename now drops the stale auto match too (daemon
  _reenrich_renamed_video_entries).

UI:
- VideoDetailModal shows the source filename and resolved TMDB id; an
  unmatched poster gets a badge (3 new video.* i18n keys x 10 locales).
  So a wrong match can actually be identified before hitting Fix match.

docs/mediacenter.md 10.1 records this and the V8-V13 follow-up backlog
(show-branch ladder, year-aware _best_match, wider sequel_variants, the
0.6-0.85 extra calls, movie grid merge, per-card rematch).
