E5 S4: Plex Discover rail-surface (default landing)

A dedicated Plex "Discover" landing — a stack of horizontal Carousel rails
served from ONE consolidated read (serve-from-DB, no live Plex/TMDB call):

- GET /api/plex/discover → continue_watching (in-progress movies + shows, most
  recently progressed) · recently_added · genres (top-N tiles) ·
  because_you_watched (recs of the most-recent watched, TMDB-enriched movie,
  resolved to library rows by guid via serve_block's resolver).
- GET /api/plex/surprise → a fresh random, scope-bounded sample for the ↻ rail.

Frontend: PlexDiscover.tsx (rails reuse the S1 Carousel + S3 PlexPosterCard;
colored genre tiles → tap to filter the grid; ↻ reshuffles the surprise rail
alone). Discover is now the root sub-view; the flat grid becomes the bookmarkable
"Browse all" secondary view (?v=browse) reached by a header search/filter (a
browse-intent flip) or the new Discover⟷Browse toggle.

resolve_recs is promoted from _resolve_recs (now cross-module). Tests:
test_plex_discover.py (rail shape/order, continue-watching, because-you-watched
+ null, surprise bounds, scope) and PlexDiscover.dom.test.tsx; plexSubUrl
round-trip updated for discover-root/grid-browse. Backend lane 393, vitest 332.

"""Plex Discover: the rail-surface read-model (E5 S4).
A consolidated payload for the dedicated Discover landing — a stack of horizontal rails:
Continue watching · Recently added · Browse-by-genre tiles · Because you watched X — plus a
separate, reshuffling Surprise-me sample. Serve-from-DB only: the recommendation rail reads the
recs the S2 TMDB engine already persisted (`PlexItem.recommendations`), never a live TMDB call, and
every card comes from the same `movie_card`/`show_card` serializers the grid uses (so rails inherit
S1's `art` + S3's rating/summary for free). The rails carry EN metadata (like the other non-grid
card paths); the HU overlay coalesces only in the main grid.
