feat(ai-report): added incomplete checks section for report package

[v-deepaktn]

Details

The report has been updated to include a new section titled "Incomplete Checks", which was previously not shown with report package.
This section now provides comprehensive information for each incomplete entry.
Relevant test cases have been added or updated to ensure these enhancements are thoroughly validated.

Added a separate function automatedChecksConversionForReportPackage in scan-results-to-unified-results.ts which will be called only for report package.
