- Add has_annexes checkbox to fichiers fragment + DB column + controllers
- Display duration on admin backoffice recap page
- Display duration on public partage recap page
- Update public TFE page for new combined duration format
- Migration 041: add duration_pages, duration_minutes, has_annexes columns; migrate data; recreate views
