Feature: Add confidence scores to Reports export

Enhanced the Rapports d'Opérations tab with detailed confidence metrics:

Backend (app.py line 272):
- Added AVG(similarity) to attendance report SQL query

Frontend updates:
- dashboard.html: Added "Confiance" column header to report table
- dashboard.js generateReport(): Display confidence as percentage (e.g., "92.3%")
- dashboard.js exportReport(): Include avg_similarity in CSV export

Reports now show complete details:
✅ Bataillon (department)
✅ Compagnie (sub_department)
✅ Confiance score (avg_similarity as %)
✅ Statut d'autorisation (is_authorized)

Addresses user request for "confidence score for each entry" in reports.
