feat(ws_handler): enhance WebSocket logging for connection events

- Added logging for WebSocket connection attempts, client connections, disconnections, and message receptions to improve traceability and debugging.
- Implemented detailed logs in readPump to capture user and client IDs during various WebSocket events, enhancing visibility into client interactions.
