Persist the info-page rich fields that were previously read LIVE from plex.metadata() on every view —
imdb_rating (IMDb-specific, vs `rating`=audienceRating), imdb_id, tagline, and full_cast
([{name,role,thumb}]) — onto plex_items/plex_shows, and serve the detail endpoints from the row.
- migration 0065: ADD imdb_rating/imdb_id/tagline/full_cast (nullable → no rewrite/lock, unlike 0064);
NULL people_enriched_at on movie/show rows so the existing cast backfill re-fetches each once and
fills the new columns.
- new app/plex/detail.py: rich_detail(meta) (moved out of browse._rich_meta so sync + serve share one
parser) + apply_rich_detail(row, meta); wired into _enrich_people_batch and the info-page lazy fill.
- item_detail: movies serve cast/IMDb/tagline/genres from the row and keep plex.metadata(markers=True)
ONLY for markers + audio/subtitle streams (so detail survives a live-Plex outage); episodes (never
enriched) still parse detail from that live meta.
- show_detail: serves cast/IMDb from the row; `related` stays live best-effort and also lazily fills a
not-yet-enriched show.
- tests: rich_detail/apply_rich_detail parsing + persistence, backfill stamping, item_detail
outage-resilience + lazy fill + episode-live, show_detail row serving. Full suite 285 pass / 2 skip;
migration verified reversible (up→down→up).
Precondition for S6's pure-DB language-aware serving.

"""Parse the "info page" rich metadata out of a full Plex metadata dict, and persist the subset that
