ver. 0.294: Remove all 12 legacy autoload/shop/ classes (~2363 lines)

Complete Domain-Driven Architecture migration:
- Phase 1-4: Transport, ProductSet, Coupon, Shop, Search, Basket,
  ProductCustomField, Category, ProductAttribute, Promotion
- Phase 5: Order (~562 lines) + Product (~952 lines)
- ~20 Product methods migrated to ProductRepository
- Apilo sync migrated to OrderAdminService
- Production hotfixes: stale Redis cache (prices 0.00), unqualified
  Product:: refs in LayoutEngine, object->array template conversion
- AttributeRepository::getAttributeValueById() Redis cache added
