Complete passkey enrollment

POST/v1/auth/mfa/webauthn/enroll/verify

Completes passkey enrollment by verifying the attestation response against the nonce sealed in enrollment_token and storing the credential under label. The first factor also returns the one-time recovery codes. Responds 400 when the token is invalid or the attestation fails to verify. Rate-limited to 10 requests per minute.
