Enhance PDF attachment detection and counting

Browse Source

Refactored `DevExpressPdfProcessor` to improve attachment detection:
- Changed `DetectEmbeddedFiles` return type to a tuple for better
  handling of attachment presence and count.
- Enhanced logic to parse `/Names` arrays and count object references
  for accurate attachment detection.
- Implemented robust search for `/EmbeddedFiles` to handle multiple
  occurrences and ensure proper context validation.

Updated PHASENPLAN.md and ROADMAP.md to reflect these changes, including
the addition of fixes for attachment detection and counting logic.

Added new tests in `DevExpressPdfProcessorTests`:
- Verified detection of multiple attachments and accurate counts.
- Ensured no crashes when processing PDFs with `/EmbeddedFiles`.

Included a new test resource (`pdfWithMoreThanOneAttachment.pdf`) for
validating multiple attachment scenarios.
