feat: artist portrait, race condition fix, and uniform button styling

- Load artist portrait from images.portrait.hash via QNetworkAccessManager
- Fix race condition: fire getArtistReleases after setArtist() clears sections,
  not before (from onArtistLoaded instead of onSearchArtistSelected)
- Apply uniform gold (#FFB232) play/shuffle button style matching album view
- Make biography scrollable (QTextEdit with max height + scroll on overflow)
- Extend track artist name parsing to handle top_tracks {display:...} format
