### Describe the bug

When the user reaches the OTP code entry view (e.g. during MFA or when confirming account signup) the autofill value is always set to `ContentType.SmsOtpCode`. This works great if the OTP code was sent via SMS but no so much if it was sent via email.

Autofill value should only be set if the delivery medium for the code is SMS. For Email codes there is no autofill support.

Start at the Authenticator OTP code entry view and trace where the autofill value is assigned as ContentType.SmsOtpCode. Verify the delivery medium before enabling SMS autofill, leave email codes without autofill support, and confirm both SMS and email code-entry flows behave as described.
