feat(customer-orders-bff): align lifecycle detail routes

docs/api/customer-order-workflows.md

@@ -21,10 +21,13 @@ This BFF exposes customer-facing order submission, status, detail, and history w
 - Default runtime target: `http://operations-service:8080`
 - Internal upstream routes:
   - `GET /internal/operations/customer/status`
+  - `GET /internal/operations/customer/orders/{orderId}`
+  - `GET /internal/operations/customer/history`
   - `POST /internal/operations/orders`
 
 ## Notes
 
 - Customer order submission currently maps `ItemIds.Count` into the upstream restaurant order workflow because the internal service contract still accepts aggregate item counts.
 - Successful submission writes into the same shared restaurant lifecycle later observed by waiter-floor, kitchen-ops, and POS projections.
+- Customer detail and history now come from dedicated lifecycle-backed upstream routes instead of projecting everything from the status snapshot.
 - Correlation IDs are preserved through Thalos session checks and operations-service calls.
