GitHub Actions 1ac3e5a444 chore: enable Cerberus security by default and fix 31 skipped E2E tests
Phase 1 of skipped Playwright tests remediation:

Changed Cerberus default from disabled to enabled in backend code
Deprecated FEATURE_CERBERUS_ENABLED env var (no longer needed)
Added data-testid and a11y attributes to LanguageSelector component
Fixed keyboard navigation timing in account-settings and user-management tests
Simplified security dashboard toggle tests with waitForToast pattern
Test results: 668 passed, 11 failed, 67 skipped (reduced from 98)
Backend coverage: 87.0% (exceeds 85% threshold)
