peter 14a44bff6e fix(plex): show-library collections get montage art too (A3)
The collection browse-tile montage queried only movie members, so show-library
collections (IMDb Popular, TMDb Trending, … in the TV library) rendered as bare colour
tiles. Union the art from PlexShow members as well (a collection lives in one library, so
exactly one side has art); fall back to the collection's own poster, then the colour hash.
Runtime stays movie-only (shows have no single duration).

Verified live: every collection now shows a montage (0 art-less tiles, was ~all the show
collections).

Gate: backend ruff clean, 5 collections tests (+ a show-collection art assertion).
