Add RFC 6238 TOTP enrollment, two-step /login flow, recovery codes, and
the amr=["pwd","mfa"] claim that propagates through refresh-token rotation.
- New endpoints: /users/me/mfa/{enroll,confirm,disable} and /login/mfa.
- /login short-circuits to a 5-min ES256 step-1 token (audience-pinned
azaion-mfa-step2) when the user has MFA enabled; real access+refresh
pair is minted only after /login/mfa.
- mfa_secret encrypted at rest via ASP.NET Core IDataProtector
(purpose=Azaion.Mfa.Secret.v1; key folder configurable via
DataProtection:KeysFolder for production persistence).
- Recovery codes (10 single-use, base32, ~80-bit entropy) hashed with
SHA-256 and stored as JSONB; constant-time compare on lookup.
- RFC 6238 §5.2 replay defense via mfa_last_used_window per user.
- Sessions carry mfa_authenticated so /token/refresh re-stamps the
amr claim correctly across the entire 30-day refresh window.
- New audit events: enroll, confirm, disable, login-success/failed,
recovery-used.
- Schema: env/db/10_users_mfa.sql adds users.mfa_* columns and
sessions.mfa_authenticated; mfa_recovery_codes mapped as BinaryJson
in AzaionDbSchemaHolder; disable path uses raw parameterised SQL to
avoid LinqToDB null-literal type-inference on jsonb columns.
E2E: 6 new tests in MfaLoginTests cover all six AC; full suite
82 passed / 0 failed / 3 intentional skips.
