feat(api): carry poster and rating through search and lists

Widen the unified search so both §9.2 halves can render a thumbnail
and a rating: TMDB results gain vote_average/vote_count from the
search bodies, library results read the #145 artwork columns, and
episodes take their series' art. GET /api/movies and /api/series gain
the same two fields for the #151 grid. Mirrors in web updated.
