Merge branch 'feat/video-type-filter'

Videos app grouping and TMDB matching fixes, plus a new toolbar filter:

- A season-like ancestor folder (numbered season, or Specials/Bonus/Extras
  -> season 0) now names the show from its own root folder, unconditionally
  — never a per-file guessit title, which cannot tell a show's real name
  from an individual episode's own one-off name when the filename carries
  no reliable ShowName/SxxExx structure. Fixes a real show's episodes and
  Specials folder alike showing up as dozens of individual "movies", each
  matched against TMDB by its own one-off title.
- The ancestor walk continues past every consecutive season-like folder,
  not just the first — a per-season Bonus folder is nested two levels
  inside the show, and stopping at the first would name the season as the
  show.
- A season spanning more than one folder (a per-book Bonus folder nested
  inside every numbered season) no longer hands out colliding episode
  numbers independently in each one.
- guessit's own episode number is not trusted when it comes from a bare
  3-digit leading number ("100" parses as season=1/episode=0, not
  episode=100) — read directly via regex instead.
- Recognizes "S1"/"S2"-style abbreviated season folders, not just full
  words ("Season"/"Saison"/"Livre") — a real show organized its later
  seasons this way and they never got the ancestor-based grouping fix at
  all.
- The TMDB match cache is no longer trusted across a movie<->show
  reclassification it doesn't know happened.
- New: an All/Movies/Series filter in the Videos toolbar, to the left of
  the search field, defaulting to "All"; wraps correctly on mobile.

Verified live against the real libraries these were found on throughout —
not synthetic reproduction alone. 430 hub tests + 667 node tests passing.
