fix(plex,audit): E30 review round 1 — the people job keeps going, HU genres everywhere, results as data

- people_enrich: a failed TMDB lookup or a dead headshot is skipped, not the end of the run (a dead
  file is marked and left for a week; three failures in a row end it); portraits wait for the Plex
  module switch; a no-Plex original keeps its own cache key, so the resize still replaces it; the job
  entry lives in the plex domain (run_people_enrich)
- person-image takes only a headshot-shaped CDN url (no query variants of one file)
- every synced row gets Hungarian genres, and a HU genre filter matches the word as picked too;
  migration 0094 fills the rows no overlay reached
- a job run's audit row carries its result as data; audit_clear / demo_reset store their counts
- one credit-column list for the prune and the enrichment order; _overlay_pass typed
- tests: batch skip + stop, HU bio stored, dead headshots, module switch, the person-image route,
  the job body, genre filter + facet write + twin fallback, tagline/summary fallbacks, audit data,
  the reader's alphabet at every remaining collated() call site
