Added Port Availability Check and Free Port Finder Function

Description: This PR introduces a mechanism to check whether a specific port is available and to recursively find a free port if needed. The isPortAvailable function checks if a port is already in use. If the port is occupied, the getFreePortWithCheck function will continue searching for an available port. This helps prevent port conflicts and ensures the application runs smoothly.
