💥  Actual behavior

We're throwing a lot of noisy logs in the output when I run fleetctl preview.

Also, the order is a bit confusing. "Waiting for host to enroll..." and other loading messages happen after "Fleet will now log you in".

I'm sure we can turn off the debug logs. Changing the log order might be a bit trickier.

Timeboxing 1 point to remove debug stuff and maybe tidy things.
