The two screens outside the navigation graph kept the old behaviour: the
system gesture left them entirely while the on-screen control beside it
stepped back.
Onboarding has a Back button and the gesture ignored it, so back from the
middle of onboarding exited the whole flow -- the app's first impression
of what its own controls mean. It now steps, and deliberately does not
intercept on the first step: there, back means leaving the app, which is
its ordinary meaning everywhere else. Silently skipping onboarding would
not be.
"Forgot your PIN?" is not a destination -- the lock screen swaps it in on
a remembered flag -- so the gesture left the lock screen from the one
place where the only other control on screen erases everything. It returns
to the PIN entry now, like its Cancel always did.
