* SecurityManager: improve logging
* Only prompt user for default 4S key
We don't really support the concept of having multiple 4S keys active, so
prompting the user to enter a non-default 4S key without even telling them
which one we want is rather silly.
* playwright: factor out helper for setting up 4S
We seem to already have about 5 copies of this code, so before I add another,
let's factor it out.
* Playwright test for dehydrated device in reset flow
This should be fixed by the previous commit, so let's check it stays that way.
