feat(i18n): the server's closed English vocabularies named in the reader's language (E30 S2)

- lib/vocab + the `vocab` locale area: TMDB crew jobs and departments, auto-tags (D1 A: the data
  stays English, the catalog is named at its one source, useTags), built-in download profiles,
  YouTube topics; held key-for-key to the backend's own lists by backendIds.contract.
- Countries by ISO code: TMDB parse stores {code, name}; rows stored before are coded from TMDB's
  own country list in one request (run_enrich); Intl names them, historic codes (YU, SU, XI…)
  from the catalog.
- Player tracks named from the language tag, forced/SDH flags and codec tail, not Plex's
  server-language displayTitle; no invented "Audio N" on the server.
- Download lifecycle notices (shared / expiring / expired / evicted) named from data; the share
  notice carries the title.
- Scheduler: the job result rides along as data and is named per key (dashboard + run notice).
- Invite status named; a render crash's notice no longer shows the engine's English message.
- Fix: YouTube links …/wiki/Humour, the tagger looked for "Humor" — Comedy never came from a topic.
