polish(ui): плавные обложки, бегущая строка длинных названий, тактильный отклик

- Coil crossfade для всех обложек (Images.crossfadeModel) — без «моргания» при загрузке
- basicMarquee для длинных названий трека (плеер и мини-плеер) вместо обрезки
- haptic feedback на play/pause и добавление в избранное (плеер, мини-плеер, карточка)
