Refactor captcha handling in tests and core functionality

Browse source 
- Updated captcha test cases to utilize the new CaptchaGet function for retrieving captcha answers, improving test reliability.
- Refactored CaptchaMake and CaptchaValidate functions to leverage a new utils package for better encapsulation and maintainability.
- Enhanced error handling and logging in captcha-related processes, contributing to a more robust user experience during authentication.
- Streamlined the captcha generation process by integrating with the utils.captcha package, ensuring consistency across the codebase.
