feat: v1.34.1 — fullscreen lyrics overlay, FsArt crossfade, lyrics toggle, contributor updates

- FullscreenPlayer: synced lyrics overlay (5-line rail, mask fade, click-to-seek)
- FullscreenPlayer: FsArt crossfade component with onLoad pattern, 300px art, next-track pre-fetch
- FullscreenPlayer: MicVocal lyrics toggle button next to heart (persisted in authStore)
- FullscreenPlayer: idle system — only close button auto-hides, cluster+seekbar always visible
- LyricsPane: refactored to use shared useLyrics hook (no double-fetch with FS overlay)
- authStore: showFullscreenLyrics field (default true)
- i18n: fsLyricsToggle key added to all 7 locales; ru2.ts removed (merged into ru.ts)
- Settings: Contributors updated (nisrael, cucadmuh, kilyabin); logout moved to Server tab as btn-danger
- theme.css: btn-danger style added
