fix(licenseinfo): accumulate all obligations per license in DOCX reports

[Aman-Cool]

Description

Fixes silent discard of multiple obligations per license in DOCX compliance reports. The fillComponentObligationsTable() method blindly overwrites instead of accumulating obligations, causing all but the last obligation for each license to vanish from generated reports.

For Apache-2.0 with three obligations (Attribution, Distribution, Patent retaliation), only the last obligation appears in the report. The other two are silently lost with no error, warning, or log entry.

Changes Made

• Changed fillComponentObligationsTable() to use computeIfAbsent() instead of put()
• Now accumulates multiple obligations per license instead of overwriting
• Uses LinkedHashMap to preserve document-defined obligation order

File changed: backend/licenseinfo/src/main/java/org/eclipse/sw360/licenseinfo/outputGenerators/DocxGenerator.java (3 lines)

Testing

• ✅ Manual test performed with Apache-2.0 CLI attachment containing 3 obligations
• ✅ Verified all obligations now appear in generated DOCX report
• ✅ Tested with multiple licenses (GPL-2.0, LGPL-2.1, MPL-2.0)
• ⭕ Unit test (existing tests cover this code path)

Impact

• All obligations per license now included in compliance reports (not just the last one)
• Legal teams get complete, accurate obligation checklists
• Eliminates silent compliance gaps that would fail IP audits
• No behavior change for licenses with single obligations
• No breaking changes to report format or API

Checklist

• ✅ Code follows project style guidelines
• ✅ All existing tests pass
• ✅ Signed-off-by added to commit (git commit -s)
• ✅ Commit message follows conventional format: fix(licenseinfo): accumulate all obligations per license in DOCX reports
• ✅ No new files added (existing file modified)

Additional Notes

This is a critical fix for compliance workflows. The bug causes legally-binding compliance reports to silently omit obligations, creating undetectable compliance gaps. The rendering code was already correct - only the accumulation logic was broken.

Hi @GMishx @Farooq-Fateh-Aftab ,Ran into this while exporting compliance reports. The DOCX generator overwrites obligations instead of accumulating them, so only the last obligation per license makes it into the report.

Bit concerning since these are used for audits. Let me know if you need any changes.

Changes looks good.
