feat(ui): рестайл всех экранов + плеер + официальные mono-логотипы сервисов

- экраны (Станции/Избранное/История/Записи/Настройки/Вход): двухцветные
  заголовки, токены темы, EmptyState, анимации появления и перестановки
- AuthScreen: брендовый локап (AppMark + RadiolaWordmark)
- PlayerBottomSheet: живой эфир — LiveEqualizer вместо перемотки,
  Crossfade трека и play/pause, pressScale, анимация избранного/записи
- кнопки музыкальных сервисов: монохромные официальные логотипы
  (vector drawable из Simple Icons CC0 + Yandex), маппинг serviceLogoRes
- DeeplinkBottomSheet: сетка сервисов с логотипами
