fix(media): a film leaves the TV library only for a film it actually names

The first tvdb-grade plan handed 12 files to the movie library, and two of them
were wrong in a way the exceptions file could not show: an episode of the
documentary series `Russia 1985-1999: TraumaZone` was renamed to the 1963 Bond
film `From Russia with Love`, and `Gundam 00 Special Edition III - Return The
World` became `Special Edition I - Celestial Being`.

Two guards, each alone insufficient:

- `title_of` salvages a short query from a long release name ("russia", "mobile
  suit gundam 00"), and tmdb() took the FIRST search result. The call site then
  compared the provider's words against that salvaged query, so any title merely
  CONTAINING the query passed. The provider's title must now be a run of words the
  FILE itself states: `Special Edition I: Celestial Being` is not in a filename
  that says `Special Edition III - Return The World`.
- tmdb() read the year from `year`/`first_air_date`, which the MOVIE search does
  not return — it returns `release_date`. Every film answer therefore arrived
  year-less and the year guard at the call site could never fire. That is how a
  1963 answer survived a filename stating 1991.

Tests: a provider answer the file does not name parks, and nothing lands in the
movie library; an answer from another year is refused. The year-from-the-wire half
is proven by the live re-plan, which now dates every movie answer.
