Multi-tablet synchronization

The Kestrel server broadcasts changes via app.Map("/api/v1/ws") to all connected tablets:

• Server A opens table 5 → server B sees table 5 grayed out instantly
• Server A sends to kitchen → server B sees lines pass to "sent"
• Customer cancels reservation → all tablets see status changed

Automatic reconnection with exponential backoff.
