Refactor MakerPointsEngine and BinanceDepthTracker for improved connection management

- Renamed connection state variable in MakerPointsEngine for clarity.
- Added connection state change listeners in BinanceDepthTracker to handle connection status updates.
- Implemented heartbeat monitoring and connection duration checks in BinanceDepthTracker to enhance WebSocket reliability.
- Introduced data staleness checks and improved error handling for WebSocket connections.
- Enhanced logging for connection events to provide better insights into connection status changes.
