fix: use iTunes lookup endpoint for explicit artist tracks

iTunes search endpoint always returns cleaned versions.
Added itunesLookupArtistSongs() using /lookup?explicit=Yes which returns
the actual explicit tracks. Used in artist profile (global search) and
artist detail page (library). Album track lookup also gets explicit=Yes.
