feat: Implement account suspension checks and improve error handling

- Added a method to check for account suspension using multiple detection methods in BrowserFunc.
- Refactored existing suspension checks to utilize the new method, reducing code duplication.
- Enhanced error handling in various functions to throw original errors instead of wrapping them.
- Improved environment variable parsing in constants to streamline validation.
- Updated login flow to optimize session restoration and error handling.
- Refined Axios request logic to include retry mechanisms for proxy authentication and network errors.
- Enhanced logging functionality to provide clearer output and error context.
- Improved utility functions with additional validation for input parameters.
