fix(video): TMDB match cache never invalidated on movie<->show reclassification

The real reason a node restart alone didn't fix already-indexed entries
after the previous commit's enrichment change: _do_media_meta_request
checked media_cache's file->tmdb mapping (keyed by content hash) and
trusted it unconditionally, before ever comparing it against the file's
*current* movie/show classification. A file whose season/episode changed
on a later scan — exactly what the Specials-folder fix does, for every
file it reclassifies from "movie" to "tv" — kept answering with its
stale, wrong-kind-of-match forever, since nothing about a reclassification
touches this cache or its key.

Now falls through to a fresh search whenever the cached media_type
disagrees with what the entry resolves to right now, rather than trusting
a mapping that predates the file's current classification.
