Subject: [PATCH] feat(BurnPdfCommandHandler): implement AddInkAnnotation for
 freehand annotations

- Added implementation for AddInkAnnotation(int page, string value) to render ink annotations from JSON.
- Deserialize ink lines and stroke color, convert points to PDF coordinates, and add as freehand annotations.
- Retained placeholder for AddInkAnnotation(Annotation pAnnotation) for future use.
