A library-agnostic home section that surfaces external global trending
(TMDB or Trakt, admin-selectable) mixing movies + series, matched to
titles in the viewer's enabled libraries. TMDB uses /trending/all/{window}
(natively mixed); Trakt merges trending movies + shows. Fetched live with
a 1h in-process cache, so no background job or stored collection — and no
per-library duplication.
Appears in the admin section gallery via its recipe presets (TMDB Trending
Today/This Week, Trakt Trending); featured -> hero via the existing flag.
