feat(catalog/products): tree-of-groups + фильтры как в MoySklad

Что добавлено:
- Слева дерево товарных групп (рекурсивное, с раскрытием), клик
  переключает фильтр ProductsPage. Клик на "Все товары" — показать весь
  каталог. Выбор группы включает её поддерево (матчинг по Path prefix
  на бэкенде, чтобы сабгруппы тоже попадали в выборку).
- Кнопка "Фильтры" разворачивает верхнюю панель с тумблерами
  (all/да/нет): Активные, Услуга, Весовой, Маркируемый, Со штрихкодом.
  Счётчик в кнопке показывает количество активных не-дефолтных фильтров.
- "Сбросить" очищает всё, кроме группы.

API:
- ProductsController.List: добавлены параметры `isMarked`, `hasBarcode`.
  `groupId` теперь фильтрует по Path-prefix (вся ветка вместо одной
  группы) — это ближе к UX MoySklad.
