Enhance order processing and event streaming capabilities

- Introduced OrderEventsService to manage order-related events and updates.
- Added SSE endpoint in OrdersController for streaming order updates to clients.
- Enhanced OrderFulfillmentOrchestrator to publish order status updates during fulfillment processes.
- Updated order field mappings to include bundled add-on information for improved order detail handling.
- Refactored OrderCard and OrderDetail components for better display of order information and status updates.

+# Order Status Updates Strategy
+
+## Current Problem
+
+The frontend was polling order details every 5-15 seconds, causing:
+- Unnecessary load on backend (Salesforce API calls, DB queries)
+- High API costs
+- Battery drain on mobile devices
+- Network waste
+
+## Root Cause
+
+**Polling is a workaround for lack of real-time push notifications.**
+
+When the backend completes provisioning and updates Salesforce, the frontend has no way to know except by repeatedly asking "is it done yet?"
+
+## The Right Solution
+
+### Phase 1: Remove Aggressive Polling ✅
+
+- Polling loop removed from `OrderDetail` (Nov 2025)
+- Order details now fetched once on mount and whenever the SSE stream notifies of a change
+- Manual refresh handled via SSE-triggered re-fetch; no background polling left in the page
+
+### Phase 2: Server-Sent Events ✅ (Implemented Nov 2025)
+
+**Architecture (now live):**
+
+```
+┌─────────────┐         ┌─────────────┐        ┌──────────────┐
+│  Salesforce │         │     BFF     │        │   Frontend   │
+│             │         │             │        │              │
+│  Platform   │──Event─▶│ Provisioning│───SSE──│  OrderDetail │
+│  Event      │         │  Processor  │        │  Component   │
+└─────────────┘         └─────────────┘        └──────────────┘

+                              │ 2. Updates Salesforce
+                              │ 3. Publishes SSE event
+                              ▼
+```
+
+**Key pieces:**
+
+- `OrderEventsService` keeps per-order subscribers alive, sends heartbeats, and emits `order.update` events
+- `GET /orders/:sfOrderId/events` exposes the SSE stream (guarded by the same JWT auth pipeline)
+- `OrderFulfillmentOrchestrator` now publishes updates when Salesforce status flips to `Activating`, when provisioning succeeds, and when failures occur
+- `useOrderUpdates` hook opens the SSE connection from the browser and triggers a re-fetch of order details when an update arrives
+- `OrderDetail` now relies on SSE instead of timers (auto-updating as soon as the backend pushes a change)
+
+```apps/bff/src/modules/orders/services/order-events.service.ts
+@Injectable()
+export class OrderEventsService {
+  private readonly observers = new Map<string, Set<InternalObserver>>();
+
+  subscribe(orderId: string): Observable<MessageEvent> {
+    return new Observable<MessageEvent>(subscriber => {
+      // ... connection bookkeeping + heartbeat ...
+    });
+  }
+
+  publish(orderId: string, update: OrderUpdateEvent): void {
+    const event = this.buildEvent("order.update", update);
+    currentObservers.forEach(observer => observer.next(event));
+  }
+}
+```
+
+```apps/portal/src/features/orders/views/OrderDetail.tsx
+const fetchOrder = useCallback(async (): Promise<void> => {
+  if (!params.id) {
+    return;
+  }
+  // ... fetch with AbortController + state updates ...
+}, [params.id]);
+
+const handleOrderUpdate = useCallback(
+  (event: OrderUpdateEventPayload) => {
+    if (!params.id || event.orderId !== params.id) {
+      return;
+    }
+    void fetchOrder();
+  },
+  [fetchOrder, params.id]
+);
+
+useOrderUpdates(params.id, handleOrderUpdate);
+```
+
+### Phase 3: Alternative - WebSockets (More Complex)
+
+WebSockets provide bidirectional communication but are more complex to implement and maintain:
+
+- Requires WebSocket server setup (socket.io or ws)
+- More complex authentication
+- Requires load balancer configuration (sticky sessions)
+- Better for real-time chat, less ideal for status updates
+
+**SSE is simpler and sufficient for status updates.**
+
+## Implementation Priority
+
+1. ✅ Remove aggressive polling (Nov 2025)
+2. ✅ Ship SSE-based order updates (Nov 2025)
+3. ⏭️ Optional: Consider WebSockets only if you need bidirectional messaging
+
+## Benefits of SSE Approach
+
+✅ **Zero polling** - No unnecessary requests  
+✅ **Instant updates** - Frontend knows immediately when status changes  
+✅ **Simple protocol** - SSE is built into browsers, no library needed  
+✅ **Automatic reconnection** - Browsers handle reconnection automatically  
+✅ **Lower costs** - Fewer Salesforce API calls  
+✅ **Better UX** - Users see status changes in real-time  
+✅ **Less backend load** - No repeated queries
+
+## Migration Path
+
+### Week 1: Remove Polling
+- [x] Remove aggressive 5-second polling
+- [x] Document interim strategy
+
+### Week 2: Implement SSE Infrastructure
+- [x] Create `OrderEventsService` in BFF
+- [x] Expose SSE endpoint `GET /orders/:sfOrderId/events`
+- [x] Publish fulfillment lifecycle events (activating, completed, failed)
+
+### Week 3: Frontend Integration
+- [x] Create `useOrderUpdates` hook
+- [x] Wire `OrderDetail` to SSE (no timers)
+- [x] Auto-refetch details on push updates
+
+### Week 4: Post-launch Monitoring
+- [ ] Add observability for SSE connection counts
+- [ ] Track client error rates and reconnection attempts
+- [ ] Review UX analytics after rollout
+
+## Testing Considerations
+
+- Test SSE connection drops and automatic reconnection
+- Test multiple tabs subscribing to same order
+- Test SSE with load balancer (ensure sticky sessions or shared pub/sub)
+- Test browser compatibility (SSE supported in all modern browsers)
+- Monitor SSE connection count and memory usage
