POST /api/v1/checkout/ always converted the customer's entire multi-store cart into orders. Add an optional store_uuids field to CheckoutSerializer — when given, checkout() only processes those stores' cart groups and only clears their items, leaving the rest of the cart intact for a later checkout. Omitted, behavior is unchanged (whole cart checks out). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
