    mainWindow: Improve accessible name of user-list button
    
    By only showing a single number, the user-list menu button clearly
    errs on the side of space efficiency and visual cleanness rather
    than discoverability. Those are not concerns for the accessible
    name though, so we can use a less concise label there.
