Update all module files to import from canonical module locations
instead of legacy re-export files:
- checkout, orders, customers routes: use module schemas
- catalog, marketplace schemas: use inventory module schemas
- marketplace, customers, inventory, analytics services: use module models

Phase 3 of storefront restructure plan - create dedicated modules for
e-commerce functionality:
- cart: Shopping cart management with storefront API routes
- CartItem model with cents-based pricing
- CartService for cart operations
- Storefront routes for cart CRUD operations
- catalog: Product catalog browsing for customers
- CatalogService for public product queries
- Storefront routes for product listing/search/details
- checkout: Order creation from cart (placeholder)
- CheckoutService stub for future cart-to-order conversion
- Schemas for checkout flow
These modules separate e-commerce concerns from core platform
concerns (customer auth), enabling non-commerce platforms.
