feat(frontend): manage Cognito users and groups, and test sign-in

The Cognito panel gains a test sign-in that shows the decoded ID and
access token claims, a groups section, and a per-user panel to enable or
disable, confirm, sign out everywhere, reset or set a password and change
group membership.

Delete confirmations (row and bulk) now say what else goes, driven by
the schema's deleteImpact, and the inspector follows list refreshes
instead of the click-time snapshot.
