Add Deezer ARL favorite artists support

Add get_user_favorite_artists(limit=200) to DeezerDownloadClient to fetch a user's favorite artists via the public API using an ARL-authenticated session (paginated, error-handled, returns deezer_id, name, image_url).

Update web_server to treat Deezer as connected if either OAuth or ARL is authenticated, and to fetch favorite artists from OAuth client when available or from soulseek_client.deezer_dl (ARL) otherwise. Fetched artists are upserted into the database and appropriate log/console messages and counters are updated.
