Add sanitized compose files for 21 rocky-docker stacks missing from the mirror

audiobookshelf, bazarr, beets, dashy, dockhand, docker-socket-proxy,
emby, ghost (+umami), jellyfin, kodi-mariadb, kopia, lidarr,
music-assistant, prowlarr, qbittorrent, radarr, seerr, sonarr, tdarr,
tinymediamanager, trilium — these run in the fleet today but had no
public entry at all. Same sanitization convention as the rest of the
repo (paths -> /path/to/..., secrets left as bare ${VAR} refs, no CA
trust details).
