- Added dependency injection for `AnnotationService`, `DocumentService`, and `AuthService` in `ReportViewer.razor`. - Improved signature button logic with dynamic appearance and feedback. - Introduced annotation checkbox overlays for marking signature fields. - Refactored signature saving and application logic into `SaveSignatureAsync` and `SubmitSignaturesAsync`. - Added `BuildFreshBaseReport` and `AddAnnotationPlaceholders` for dynamic report creation. - Implemented annotation-specific signature placement with `AddSignatureAtAnnotation`. - Enhanced state management for annotations and signature overlays. - Updated `app.css` with styles for annotation checkboxes. - Added cache-control headers and versioned JavaScript in `index.html`. - Improved `receiver-signature.js` with annotation checkbox management, optimized signature pad logic, and debugging utilities. - Performed general code cleanup and optimization for maintainability.
