func ValidatePort

func ValidatePort(portStr string) (string, error)

ValidatePort checks if the provided port string is valid and returns a clean, normalized version. It accepts formats like ":8080", "localhost:8080", "127.0.0.1:8080", or just "8080". Returns the normalized port format (":PORT") and an error if the port is invalid.
