ui(products-list): убрать фильтр «Со штрихкодом», добавить «Закупочная цена от/до»

Поскольку штрихкод теперь обязательный (минимум 1 у каждого товара),
фильтр «Со штрихкодом» бессмыслен — убран из UI и контроллера.

Вместо него — два MoneyInput «Закупочная цена от/до» в панели
фильтров. Использует символ валюты по умолчанию из настроек
организации и уважает AllowFractionalPrices.

Backend: ProductsController.List принимает purchasePriceFrom /
purchasePriceTo (decimal?), применяет ≥ / ≤ к PurchasePrice;
параметр hasBarcode удалён.
