YouTube enricher: consistent log output with the other video workers

- Logger renamed video.youtube_enrichment -> video_enrichment.youtube (same
  namespace as video_enrichment.worker).
- Per-item lines as it dates each video — 'Dated <channel> '<video>' -> <date>'
  / 'No date for …', mirroring the workers' 'Matched <kind> '<title>' -> TMDB
  ID: …'. (Phase lines kept for context: enriching / proxy returned / done.)
