refactor: migrate schemas to canonical module locations
Migrate remaining legacy schemas to their respective modules:
Marketplace module (app/modules/marketplace/schemas/):
- letzshop.py: Letzshop credentials, orders, fulfillment, sync
- onboarding.py: Vendor onboarding wizard schemas
Catalog module (app/modules/catalog/schemas/):
- product.py: ProductCreate, ProductUpdate, ProductResponse
Payments module (app/modules/payments/schemas/):
- payment.py: PaymentConfig, Stripe, transactions, balance
Delete legacy files:
- models/schema/letzshop.py
- models/schema/onboarding.py
- models/schema/product.py
- models/schema/payment.py
- models/schema/marketplace_product.py (re-export)
- models/schema/marketplace_import_job.py (re-export)
- models/schema/search.py (empty)
Update imports across 19 files to use canonical locations.
