feat: Display candidate name from CV data instead of filename

- Added CandidateName field to CVCheckDto
- Extract candidate name from ReportJson or ExtractedDataJson
- Dashboard now shows actual candidate name for JSON uploads
- PDF export uses candidate name from report

This fixes the issue where JSON files showed their filename (e.g.,
"CLEAN-001") instead of the actual candidate name from the CV data.
