Onboarding · Flows and highlights: focus that holds as the flow turns, a tip that closes

navigation::Wizard keeps one focus handle for Next and Finish, so a
second press on the step before last finishes; Back that reaches the
first step, and a finished step picked by key, hand focus to Next.
Popover::with_opener hands its content a close that gives focus back:
Got it closes the hotspot's tip before the owner hides it, and the
event details close before Edit and Delete run, so focus never lands
on a panel that left the tree. The wizard's count and the setup
checklist's tally name their selectors after their words, and the bar
takes the count's own value.
