feat(filters): быстрый выбор категории + очистка поиска

- Кнопка-«категории» (круглая, акцентная рамка, иконка SlidersHorizontal) СЛЕВА от
  чипа «Все» — на экранах Радио и Чарты. Открывает шторку со списком всех категорий
  (Радио — жанры, Чарты — стили) + поиск, чтобы не листать чипы. CategoryPicker —
  переиспользуемый компонент с поиском и отметкой выбранного.
- SearchBar: анимированная кнопка очистки (X, scale+fade появление, haptic) при
  непустом запросе.
