Fix calibre: replace NFS volumes with systemd automount bind mounts

SQLite (Calibre Notes DB) fails with SQLITE_IOERR on soft NFS when unRAID
drives spin down. Replace Docker NFS named volumes with bind mounts to
/mnt/nas_media (CIFS via systemd automount), same pattern as backrest and
filebrowser-colleen-hd. systemd handles drive reconnection independently.
