feat(telnet_server): improve error handling and connection management

Browse Source 
- Catch OSError alongside ConnectionError in connection processing to handle more network errors
- Move client_info retrieval inside try block to prevent AttributeError on failed connections
- Replace bare except with specific exceptions (OSError, ConnectionError, asyncio.TimeoutError)
- Improve error logging to include specific exception details and client information
