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

 - 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.

 ## Domain-Specific Candidate Features
-- Order lifecycle consistency and state transitions.
-- Customer order detail and history views that stay aligned with operations-service workflows.
-- Kitchen queue and dispatch optimization hooks.
+- Customer-facing projection over the shared restaurant lifecycle.
+- Customer order detail and history views that stay aligned with waiter, kitchen, and POS state changes.
+- Cross-app order continuity from customer submission to kitchen preparation and POS payment.
 - Operations control-plane policies (flags, service windows, overrides).
-- POS closeout and settlement summary alignment.

 ## Known Limitations
 
-- Customer-orders now delegates workflow snapshots to `operations-service`, but the upstream operations adapter still serves deterministic demo data rather than database-backed state.
+- Customer-orders now delegates workflow snapshots to `operations-service`, which projects persisted shared lifecycle state from `operations-dal`.
+- Kitchen and POS visibility still depend on the remaining Stage 46-48 restaurant flow tasks being wired end-to-end.
 - Demo PostgreSQL seeds validate integration contracts and smoke determinism, but do not yet imply full persistence implementation parity.
