Native auth: Update Email OTP MFA to Match EC Implementation, Fixes AB#3351233 (#2760)

This PR updates the SDK to match the latest flow from EC.

In this new flow, the developer must always supply an auth Method to the
/oauth2/v2.0/challenge endpoint which means once the .mfaRequired error
is received from token endpoint, the /oauth2/v2.0/introspect endpoint
needs to be called to retrieve the methods which are automatically
returned to the external developer.

Furthermore, whenever calling the /token endpoint is called with an MFA
Email OTP code, the grant type should be mfa_oob
