fix(dashboard): leave the temporary-account state once the account is saved

Saving a temporary account from the user menu promoted the user in place
without a reload, but Home kept its Save session warning (reopening the
save dialog for a saved account) and Account and Security stayed without
their password and email cards until the page was reloaded. The dashboard
now reacts to account-saved, which fires after the user is updated.
