This commit replaces the existing PDF.js-based viewer with the DevExpress DxPdfViewer component, introducing significant improvements to the UI, state management, and signature handling. Key changes: - Integrated DevExpress.Blazor.PdfViewer and removed PDF.js dependencies. - Updated HTML structure to use `DxPdfViewer` and new overlay layers. - Refactored zoom and navigation logic to use DevExpress APIs. - Overhauled signature button rendering and positioning logic. - Added dynamic scaling for applied signatures based on zoom level. - Introduced `requestOverlayRefresh` for efficient overlay updates. - Added new CSS styles for the DevExpress viewer and overlays. - Refactored `pdf-viewer.js` to remove legacy PDF.js logic. - Improved performance with `requestAnimationFrame` and optimized event handling. - Added a `dispose` method for proper cleanup of resources. - Enhanced error handling and accessibility for signature buttons. - Removed redundant code and improved overall maintainability.
