Refactor smartsocket implementation for improved WebSocket handling and message protocol

- Updated test files to use new testing library and reduced test cycles for efficiency.
- Removed dependency on smartexpress and integrated direct WebSocket handling.
- Enhanced Smartsocket and SmartsocketClient classes to support new message types and authentication flow.
- Implemented a new message interface for structured communication between client and server.
- Added external server support for smartserve with appropriate WebSocket hooks.
- Improved connection management and error handling in SocketConnection and SocketRequest classes.
- Cleaned up code and removed deprecated socket.io references in favor of native WebSocket.
