feat(blacklist): add grayout styling for blacklisted artist tracks

- TrackRow: Add isBlacklisted prop with grayout styling and ban icon
- VirtualizedTrackList: Check blacklist status for each track
- PlaylistDetailView: Gray out and restrict actions for blacklisted tracks
- AlbumDetailView: Apply album-level blacklist check to all tracks
- HomeView: Gray out blacklisted tracks in Continue Listening section
- ArtistDetailView: Banner shown when viewing blacklisted artist page

Blacklisted tracks show reduced opacity, ban icon instead of track
number, and restricted menu actions (navigation only, no playback).
