Update PDF metadata handling in PdfResultPackageService

Browse Source 
Introduce functionality to remove and replace metadata in the
resulting PDF document. After loading the document with
`PdfDocumentProcessor`, the metadata fields (`Author`, `Creator`,
`Producer`, `Title`, `Subject`, and `Keywords`) are cleared or
replaced with values indicating the document was processed by
the "DXApp" system. This ensures proper attribution and removes
any association with the original document creator.
