Subject: [PATCH] Enhance PDF processing and report integration

Refactor `PdfResultPackageService` to improve PDF handling:
- Load the main document into `PdfDocumentProcessor`.
- Remove original metadata to attribute the result to `DXApp`.
- Replace report file attachment with appending report pages.
- Use a temporary processor to determine report page count.
- Add logging for appended pages and total page count.
- Update save operation to include detailed logging.

Removed the functionality to attach the report file as a PDF attachment.
Improved overall usability, traceability, and document attribution.
