Refactor QPDFJob::checkConfiguration code to improve readability and consistency 

Replaced `else if` chains with standalone `if` statements for clarity. Updated conditional checks with modern coding practices, such as using `.contains()` instead of `.count()`. These changes enhance code maintainability and ensure better style consistency.
