Summary0011228: merchant backend should return challenges and tan channels in order (email before SMS)
DescriptionFor us, it's always cheaper to do email compared to SMS.

In the `ChallengeResponse` and `mandatory_tan_channels`, the backend should return the channels in order of preference.

The UI relies on that order to render the MFA prompts in sequence.
