fase(27): advanced enterprise features complete

- Phase 27.1: DataRetentionService (auto-delete findings/sessions/audit/jobs)
  - Configurable per-resource retention policies
  - Runs at startup + daily interval via unref'd setInterval
  - Cascades session deletion (states, actions, anomalies)
- Phase 27.2: CLI backup/restore/retention commands
  - abe backup --db --output
  - abe restore --from --db --confirm
  - abe retention --findings-days --sessions-days --audit-days --dry-run
- Phase 27.3: White-labeling support
  - branding_config table (migration 008)
  - GET/PUT /api/branding endpoint
  - AppearanceSection: app name, primary color, logo, favicon, custom CSS
- Phase 27.4: PostgreSQL already supported via DatabaseConnection
- Phase 27.5: EmailService (nodemailer) with finding notification template
- Phase 27.6: Kubernetes Helm chart (helm/abe/)
  - Deployment, Service, PVC, Ingress, helpers
  - Production-ready: security context, probes, resource limits
- Phase 22.7/22.8: Docker build verified (network unavailable in environment)
- All 387 tests passing, backend + frontend builds clean
