Two production-only gaps reported against the packaged 0.22 build:

1. Trailers showed YouTube "Error 153 — Video player configuration
   error". YouTube requires a Referer on /embed requests; the packaged
   app loads the renderer from file://, which never sends one (dev works
   because the origin is localhost). The Electron main process now
   injects the project site as Referer for YouTube embed hosts when the
   header is absent (request-header-overrides.service.ts, registered at
   startup via registerStaticHeaderShims). Existing Referers are never
   overwritten, other hosts untouched.

2. Descriptions vanished for content whose original language differs
   from the app language: TMDB does not fall back on missing
   translations, so a Russian-only series has empty overviews in en-US.
   When the app-language payload carries no text, the enrichment
   refetches once in the content's original_language and fills ONLY the
   missing text fields (tmdb-language-fallback.ts): details overview,
   season overview and per-episode names/overviews. Genres, credits and
   artwork stay in the app language; both language rows share the cache.

Tests: 3 new shim cases in request-header-overrides.service.spec.ts,
new tmdb-language-fallback.spec.ts (9 cases). Docs updated
(tmdb-metadata-enrichment.md).
