fix: extend sticky nav bars edge-to-edge with sidebar

- ArtistDetailView: jump-nav now flush with sidebar (margin -44px left)
- FavoritesView: favorites-nav flush with sidebar
- LocalLibraryView: jump-nav flush with sidebar
- SettingsView: settings-nav flush with sidebar
- All navs compensate for both main-content and view padding
- Radio animation: faster floating messages (1.2s), infinite loop
