Maurice b3113e66b9 feat(native): buying TREK Cloud in the app asks for the password of the new TREK and opens it signed in
The claim screen takes the password (TREK's policy, checked before anything is
bought) and sends it with the purchase; the control plane answers with a
one-time welcome code, which the app hands to setServer. iOS and Android open
the instance's welcome page with it once after the first page, which signs the
buyer in. Without the code (a restore, an older control plane) the app opens
the instance as before.
