Update WebSocket configuration and enhance connection handling in WalletWebSocketService

- Increased reconnect delay from 1 second to 2 seconds and reduced max reconnect attempts from 5 to 3 to minimize server load.
- Improved logging messages for connection status and abnormal closures, providing clearer insights during reconnection attempts.
- Added a ping mechanism to test connection stability and handle network connectivity issues more effectively.

These changes enhance the reliability and performance of the WebSocket service, contributing to a better user experience.
