Implements automatic configuration of 2FA enforcement via Authentik API:
**Features:**
- Forces users to configure TOTP authenticator on first login
- Supports multiple 2FA methods: TOTP, WebAuthn, Static backup codes
- Idempotent: detects existing configuration and skips update
- Fully automated via Ansible deployment
**Implementation:**
- New task file: ansible/roles/authentik/tasks/mfa.yml
- Updates default-authentication-mfa-validation stage via API
- Sets not_configured_action to "configure"
- Links default-authenticator-totp-setup as configuration stage
**Configuration:**
```yaml
not_configured_action: configure
device_classes: [totp, webauthn, static]
configuration_stages: [default-authenticator-totp-setup]
```
**Testing:**
✅ Deployed to dev server successfully
✅ MFA enforcement verified via API
✅ Status: "Already configured" (idempotent check works)
Users will now be required to set up 2FA on their next login.
