[balsa/gtk4: 55/246] balsa-message: Manage menu settings

    balsa-message: Manage menu settings
    
    In the "paper-clip" attachments button, selecting "force inline" should
    clear any selected part button, clearing it should select "complete
    message", and selecting any individual part should clear "force inline".
    
    Ideally, changing the selection in the parts tree-view should also
    update the attachments button menu, but that is challenging!
