Implement updateWalletBalance method in PaymentService and deprecate AuthService method

- Added updateWalletBalance method in PaymentService to handle wallet balance updates from WebSocket notifications, improving wallet management.
- Deprecated the existing updateWalletBalance method in AuthService, redirecting calls to the new PaymentService method for better consistency and maintainability.
- Updated WalletWebSocketService to utilize PaymentService for balance updates, ensuring accurate wallet state management.

These changes enhance the architecture of wallet balance handling and streamline the update process across services.
