    online-accounts: add an offline message label
    
    When offline, we currently block the new accounts listbox
    so that users can't add new accounts. There is, however,
    no visual indication that we're offline, besides the listbox.
    
    Fix that by adding a descriptive label that's only visible
    when offline.
