settings: let users delete their accountHEADmaster

A Delete account entry on the security tab leads to /settings/delete,
which warns what's lost, asks for the username (and PIN when set) and
calls the server's POST /delete, then logs out. The page resets to the
(app) layout so its form isn't nested in the settings save form.
