feat(lyrics): тексты песен внутри приложения через LRCLIB

- LrcLibApi (api/get + api/search, User-Agent), DI @Named(lrclib) Retrofit
- LyricsRepository.fetchLyrics -> LyricsResult (plain/synced/instrumental)
- LyricsViewModel + LyricsSheet (загрузка/инструментал/найдено/не найдено),
  прокрутка + атрибуция LRCLIB
- кнопка «Текст песни» открывает встроенный экран (плеер + деталь трека чартов),
  вместо ссылки в браузере
