Description

What happened:
In pkg/api/handlers/websocket.go:176-180, Hub.Close() only closes h.done causing Hub.Run() to return. But Run() is the only path that closes client.send channels via the unregister case. When Run exits, no client.send channel is closed, so every writer goroutine blocks forever on <-client.send until TCP connections are forcibly closed.

What I expected:
Before closing h.done, Hub.Close() should iterate h.clients under h.mu.Lock() and close every client.send channel to unblock writer goroutines immediately.

Steps to reproduce:

1. Connect multiple WebSocket clients
2. Call Hub.Close()
3. Observe writer goroutines remain blocked until TCP connections are forcibly closed
