Migrate QA documentation from docs/qa-testing/ to docs/qa/:
- Remove obsolete screenshots from previous testing rounds
- Remove outdated DEFECTOS-QA.md (issues have been resolved)
- Add new QA report for student activation flow testing
- Reorganize qa-testing folder with updated structure
New documentation:
- QA-REPORT-STUDENT-ACTIVATION-FLOW.md: comprehensive test report
covering activation UI, code validation, expiry handling,
and admin manual activation features
This cleanup removes 30+ obsolete screenshots and consolidates
QA documentation in a cleaner structure.
