Implement preloader enhancements for quantity management and increment version code to 4.72.741

This commit introduces a loading overlay for heavy page loads in the quantity management section, improving user experience during data retrieval. Additionally, a loader is displayed upon clicking specific links to enhance feedback while waiting for server responses. Minor adjustments are made to the JavaScript handling of anomalies, ensuring smoother interactions. The version code is incremented to reflect these updates.
