chore: refactor tests to improve clarity and reliability

- Removed unnecessary test.skip() calls in various test files, replacing them with comments for clarity.
- Enhanced retry logic in TestDataManager for API requests to handle rate limiting more gracefully.
- Updated security helper functions to include retry mechanisms for fetching security status and setting module states.
- Improved loading completion checks to handle page closure scenarios.
- Adjusted WebKit-specific tests to run in all browsers, removing the previous skip logic.
- General cleanup and refactoring across multiple test files to enhance readability and maintainability.
