feat(phase3): Classification en masse, Export STIX, Audit Logs

Browse Source 
🎯 NOUVELLES FONCTIONNALITÉS ENTERPRISE SOC:

• 🏷️ Classification en Masse
  - Sélection multiple d'IPs
  - Classification simultanée (jusqu'à 1000 IPs)
  - Barre de progression en temps réel
  - Export CSV des classifications
  - Logs d'audit automatiques
  - Composant: BulkClassification.tsx

• 📤 Export STIX/TAXII 2.1
  - Format standard pour Threat Intelligence
  - Compatible avec les plateformes TIP
  - Export par IP ou par incident
  - Bundle STIX complet avec:
    • Indicators (IPv4 addresses)
    • Observables
    • Relationships
    • Identity (SOC)
    • Marking (TLP:AMBER)
  - Alternative: Export MISP
  - Utilitaire: STIXExporter.ts

• 📝 Audit Logs Complet
  - Table ClickHouse: audit_logs
  - Tracking de toutes les actions:
    • CLASSIFICATION_CREATE / BULK_CLASSIFICATION
    • EXPORT_CSV / EXPORT_JSON / EXPORT_STIX
    • INVESTIGATION_START / COMPLETE
    • INCIDENT_CREATE / UPDATE / CLOSE
  - Filtres: user, action, entity_type, période
  - Statistiques d'activité
  - Rétention: 90 jours
  - API: /api/audit/logs

🔧 COMPOSANTS CRÉÉS:
• frontend/src/components/BulkClassification.tsx (340 lignes)
  - Interface de classification multiple
  - Progress bar
  - Export CSV
  - Tags prédéfinis
  - Slider de confiance

• frontend/src/utils/STIXExporter.ts (306 lignes)
  - Génération bundle STIX 2.1
  - Export IPs et incidents
  - Format MISP alternatif
  - UUID v4 generator

• backend/routes/audit.py (230 lignes)
  - POST /api/audit/logs - Créer un log
  - GET /api/audit/logs - Liste avec filtres
  - GET /api/audit/stats - Statistiques
  - GET /api/audit/users/activity - Activité par user

• deploy_audit_logs_table.sql (180 lignes)
  - Schema audit_logs
  - Index optimisés
  - Vues: view_audit_stats, view_user_activity
  - TTL 90 jours
  - Exemples d'insertion

📊 PERFORMANCES:
• Build size: 495 KB (148 KB gzippé)
• Classification en masse: 10 IPs/batch
• Audit logs: 90 jours de rétention
• STIX export: < 1s pour 100 IPs

✅ Build Docker: SUCCESS
