- Refactored MgGridInfoPanel for DevExpress theme compatibility and improved usability; streamlined HTML/CSS, added OnDataItemChanged event, and enhanced empty state handling.
- Updated CSS to use theme variables, improved responsive grid and table styling, and enhanced integration with DevExpress components.
- GridShippingDocumentInfoPanel now uses OnDataItemChanged to load a random PDF per row selection; table layout and totals improved.
- Optimized pdfViewer.js to cache rendered PDFs, skip redundant renders, and improve logging and error handling.
- Added empty helper classes for future extensibility.
- Minor: MainLayout now uses RefreshMainLayout for UI refresh after auto-login.
