Items like vouchers may have no GTIN at all. Previously, the placeholder
product was only created when there were missing GTINs, causing a NOT NULL
constraint violation for items with gtin=None.
Now we also check for items without GTIN and create a placeholder for them.

Replaces the "fail on missing product" behavior with graceful handling:
- Orders import even when products aren't found by GTIN
- Unmatched items link to a per-vendor placeholder product
- Exceptions tracked in order_item_exceptions table for QC resolution
- Order confirmation blocked until exceptions are resolved
- Auto-matching when products are imported via catalog sync
New files:
- OrderItemException model and migration
- OrderItemExceptionService with CRUD and resolution logic
- Admin and vendor API endpoints for exception management
- Domain exceptions for error handling
Modified:
- OrderItem: added needs_product_match flag and exception relationship
- OrderService: graceful handling with placeholder products
- MarketplaceProductService: auto-match on product import
- Letzshop confirm endpoints: blocking check for unresolved exceptions

Restructured create_letzshop_order to follow the "validate first, then write"
architecture pattern:
Phase 1 (Read-only validation):
- Check if order already exists
- Parse all inventory units and collect GTINs
- Batch query all products by GTIN (single query instead of N queries)
- Validate all products exist - raise ValidationException BEFORE any writes
Phase 2 (Database writes):
- Only after all validation passes, create customer, order, and items
This ensures if validation fails, no database modifications happen, so the
endpoint/task simply doesn't commit - no rollback needed.

Add the missing method to OrderService that was being called
from the admin orders API endpoint.

- Services now use db.flush() instead of db.commit() for database operations
- API endpoints handle transaction commit after service calls
- Remove db.rollback() from services (let exception handlers manage this)
- Ensures consistent transaction boundaries at API layer
This pattern gives API endpoints full control over when to commit,
allowing for better error handling and potential multi-operation transactions.
