Mark Rachapoom c38d1281d4 fix: send Origin header in gateway WebSocket connections
The Node.js ws library doesn't send an Origin header by default.
When the client identifies as openclaw-control-ui, the gateway
enforces origin checks and rejects connections with missing origin.

Pass the gateway URL as the Origin header so the gateway's
local-loopback check sees a valid loopback origin and allows it.

Bump to v2.3.20.
