Remove YouTube integration from backend and deployment config

Drops the YouTube-backed second catalog source entirely: the Local/External split on Track/Album collapses into single concrete entities, Artist/TrackArtist/ExternalTrack/ExternalAlbum and the YouTube service/download pipeline (yt-dlp, MassTransit consumer, routing slip) are deleted, and mixes now source discovery only from local listening history. Includes the RemoveYouTubeIntegration EF Core migration and matching Worker/deploy/compose cleanup (no more yt-dlp/python/deno in the Worker image, no thumbnail-cache/YtDlp config sections).
