Refactor real-time chat to use websockets

[dotnize]

Our real-time chat implementation currently uses short-polling which is very inefficient. We need to use websockets.

• Nitro Websockets or a separate websocket service?

Hey @dotnize,
I would like to work on this issue. Could you pls assign this issue to me.
Socket.io would be a best choice for implementing real-time chatting.
Thank you.
