feat(domain): pricing model rename and new fields (Phase3a)

Подготовка к новой модели цен сторонняя система-style:
- Product.PurchasePrice → ReferencePrice (справочная закупочная,
  не обязательная). + ReferencePriceUpdatedAt для 30-дневного таймера.
- Product.+ Cost numeric(18,4) — себестоимость по скользящему среднему.
- Product.+ LastSupplyAt — UTC последней Posted приёмки.
- ProductGroup.+ MarkupPercent (5,2) — % наценки на cost для авто-розничной.
- Organization.+ MultiplePriceTypesEnabled (default false) и
  ShowReferencePriceOnProduct (default true).
- SupplyLine.+ RetailPriceManuallyOverridden + RetailPriceOverride —
  отметка ручной правки розничной в строке приёмки.

Миграция Phase3a_PricingModel: RENAME + AddColumn'ы. Logic перерасчёта
себестоимости, автонаценки, recalc-endpoint и Hangfire job — следующими
коммитами.

DTO/контроллеры/OtherSystem-импорт/UI поля переименованы в referencePrice
(включая фильтры списка товаров). UI-логика следующего коммита будет
показывать Cost и кнопку «привести розничную к себестоимости»; пока
referencePrice работает как раньше.
