feat: складские цены и «только наличие» — настройки уровня проекта

Добавлен чекбокс «Складские цены» (по аналогии с «Аренда»), управляющий
показом складских цен во всех ценовых интерфейсах конфигурации, включая
CSV-экспорт. «Только наличие» перенесён из настроек цен конфигурации в
настройки проекта и активен только при включённых складских ценах.
