feat: Модуль "Справочник товаров"

Создать структуру базы данных для товаров:

        Поля: наименование, штрих-код, срок годности, размеры, единицы измерения, производитель, категория товара, температурные условия хранения, акции (тип "1+1", "2+1").

 Реализовать функционал:
        Добавление, редактирование и удаление карточек товаров.
        Проверка на дублирование данных (штрих-код).
        Валидация данных (например, срок годности).
