feat: V13 — per-card "re-match this one file" (MNP 0.13)

A one-click alternative to the full "Fix match" search-and-pick flow, and
reachable without SSH (`meshbay-node video rematch` clears a whole group).

- MNP 0.13: tmdb_rematch / tmdb_rematch_ack (additive — an older node
  logs "unknown type", the button just does nothing). OP_TMDB_REMATCH,
  signed like tmdb_override (media_cache is shared node-wide).
- media_cache.drop_tmdb_match(file_id): forgets the match AND the
  override marker — deliberately stronger than clear_file_tmdb, since the
  operator is explicitly asking for a fresh resolution.
- webrtc_server: _do_tmdb_rematch / _admin_exec_tmdb_rematch, dispatch +
  admin-response routing, broadcasts tmdb_rematch_ack.
- transport.js: rematchTmdbMatch(fileId, signFn); 'tmdb_rematch' in the
  admin-op allowlist; tmdb_rematch_ack handled like tmdb_override_ack.
- video-app.js: a "Re-match" button beside "Fix match" in the detail
  modal (isNodeAdmin), then bumpMediaMetaGeneration(). video.rematch_one
  key in all ten locales.

docs/mediacenter.md §10.1: V8–V13 marked done.
