/**
* Redeem a single-use recovery code for account recovery.
*
* The user is authenticated (aal1) but locked out of step-up because they lost
* their authenticator/passkey. On a valid code we mark it used and DELETE all
* of the user's MFA factors via the admin API. GoTrue logs the user out of all
* sessions when a verified factor is deleted, so the client signs out and
* returns to /login; after signing back in (aal1, zero factors) the middleware
* forces fresh enrollment. We never fabricate an aal2 JWT.
