Update dependencies and enhance App component functionality

- Added new dependencies: @polkadot/util and @gear-js/api to package.json and example/package.json.
- Implemented a test function in App component to interact with GearApi for balance transfer.
- Updated transaction signing logic to support both raw and payload types.
- Refactored Wallet class to improve socket connection handling and transaction management.
- Enhanced WalletStore by removing unnecessary listener setup code.
