Connection Management Refinements and Error Handling Improvements

This PR implements several key changes, include:

Enhanced Error Handling

• More detailed logs for better debugging and error analysis.

Simplification and Refactoring

• Critical methods such as Connection::close and Connection::accept have been simplified and refactored for clarity.

Precise Timeout Management

• std::chrono::milliseconds implemented for more accurate timeout settings.

Improved Protocol Management

• Better handling of connection states and protocol management.

Robust Socket Closure

• Addition of socket.cancel(); in Connection::closeSocket() ensures cancellation of pending asynchronous operations, increasing safety during socket closure.

Safe Message Sending

• State of the socket is now checked before sending messages, preventing attempts to write on closed sockets.

Optimized Thread Safety

• Utilization of std::scoped_lock and std::unique_lock optimized for safer thread handling.

Improved IP and Timeout Handling

• Enhancements in IP management and more efficient timeout handling.
