feat(PDFBurner): support unstructured annotations and simplify processing

- Added `UnstructuredAnnotations` property to handle annotations without structured IDs
- Changed default `hasStructuredID` to `False`, set to `True` only after successful parsing
- Updated `AddInstantJSONAnnotationToPDF` to process annotations directly instead of grouping by receiver
- Simplified logic for reversing annotations and applying seal positioning
