/**
 * Tests for Multi-Factor Authentication (TOTP + backup codes):
 *   - Enrolment flow (start + confirm) and rejection of wrong OTPs
 *   - Login flow: password -> mfa_pending cookie -> /login/mfa -> session cookie
 *   - Replay prevention: same (user, code, window) refused twice
 *   - Backup code single-use semantics and remaining count
 *   - Lockout after repeated failures
 *   - Partial-auth session: mfa_pending token rejected on non-MFA routes
 *   - Admin reset endpoint
 *   - SSO bypass toggle
 *   - CLI reset helper (direct import, no subprocess)
