feat(app): the warning that a session was ended for its proofs

A password sign-in whose account carries the warning (a session ended
for ten wrong proofs in a row) shows it before the sign-in is put in
place: when, what it means, and to change the password if it wasn't
the owner. Dismiss clears it on the instance through the held-back
session; Remind me later signs in and keeps it. The account section
shows it above the change of password, with Dismiss, while it stands.
Nothing identifies the session or its device.
