Stufe B routed /api/meta/lookup through the combined resolver, so the editor's 'Deezer' button could silently return MusicBrainz data while the status said 'von Deezer'. The editor already has a dedicated 'MusicBrainz' button, so keep the two explicit and honest: Deezer button = Deezer only. The combined Deezer→MusicBrainz→clean resolver stays on the DOWNLOAD paths.
