siftlode/backend/tests/test_plex_person.py

"""DB-backed regression (E5 S4): GET /api/plex/person/{name} returns a cast/crew member's
filmography — movies + shows in the ENABLED libraries whose cast OR directors include the name,
each carrying the caller's watch-state, plus the cached headshot. Also covers `_content_libs`
scoping (disabled libraries excluded) and the kind filter (episodes are not movies).

Uses the DB lane (`db` fixture) — skipped when no Postgres is reachable.
