The main settings list carried both an Accounts row and a switcher row
beside it — two account controls at the top level, one of them opening
the screen the other belonged on. The switcher row moves to the top of
the accounts screen as a Current Account section, where the selection
it names sits directly above the checkmarked row it corresponds to.
The subscriptions-settings row and the macOS sidebar footer keep
theirs: those are contextual surfaces, not the settings list.
