refactor(v2): migrate get_artist_detail to v2

Path C: legacy command called client.get_artist_detail with the
hard-coded mobile defaults of limit=1000, offset=0 to populate the
suggestions panel's playlists and tracks_appears_on. No close v2
equivalent existed (v2_get_artist_with_albums uses
extra=albums only), so add v2_get_artist_detail that goes through
QbzCore -> QobuzClient::get_artist_detail directly.
