John Mizerek 008b6d45b2 Add polling service for order status notifications
Client-side implementation:
- New service: order_polling_service.dart - Timer-based polling every 30s
- Updated AppState: track active order ID and current status
- Cart integration: start polling after order submission
- In-app notifications: color-coded SnackBar for status changes
- Notification widget: animated banner (created for future use)

Status notification colors:
- Blue = Submitted (1)
- Orange = Preparing (2)
- Green = Ready (3)
- Purple = Completed (4)

Polling workflow:
1. User submits order → polling starts with status=1
2. Every 30s: check backend for status changes
3. On update: show notification + update AppState
4. Continues until order completed or app closed

Simple polling approach (Option 2) with planned migration to self-hosted WebSocket push for instant updates.
