feat(nav+fav): порядок меню, анимация иконки при выборе, индикатор на избранном

- Порядок нижнего меню: Радио · Избранное · История · Чарты · Запись · Настройки.
- Иконка вкладки при выборе делает упругий scale-«поп» (spring MediumBouncy) —
  в нижнем баре и боковом рейле.
- На экране «Избранное» играющая станция теперь подсвечивается так же, как на
  главной: вращающееся свечение под обложкой + индикатор-эквалайзер в углу
  (FavoritesViewModel отдаёт playingStationId/isPlaying из PlayerController,
  FavoritesScreen передаёт isCurrent/isPlaying в StationCard).
