Two gaps the pin left, on both platforms:
1. Search still showed the wrong same-name artist's photo. The library search
now prefers the pin's Deezer picture for a pinned artist (web: search.js
artist cards; android: LibrarySearchContent via SearchViewModel overrides).
2. Similar Artists were "weird" — they come from Last.fm keyed to the (merged/
wrong) Navidrome artist. When pinned, use Deezer "related" of the pinned
artist instead (new deezerRelatedArtists / ItunesClient.lookupRelatedArtists).
Also: web Similar Artists now render with profile pictures (avatar chips), like
the Android app, instead of plain text chips.
