Remember unavailable movies and auto-grab them later (wishlist)

When Smart Search finds no good copy of a movie (unreleased / only CAMs), we
now record it instead of dropping it:
- New Wanted model + migration (dedup by tmdbId, status wanted|fulfilled).
- POST /__api/search/releases remembers a movie when it returns no options,
  and the UI confirms it was added to the wishlist.
- controller/wantedWatcher re-runs Smart Search for wishlisted items every 6h
  (and on boot); when a good copy appears it queues the recommended release,
  which then flows through the normal download + organize pipeline, and marks
  the item fulfilled.
- GET/DELETE /__api/search/wanted to view/remove the wishlist.
