    status/network: Ensure the Cancel button passes undefined to close()
    
    The parameter to `ModalDialog.close(timestamp)` is optional. But when
    invoked via the network dialog's Cancel button it was receiving an
    implicit parameter value that's definitely not a timestamp:
    
    ```
    [0x560f18af0c50 StButton.modal-dialog-linked-button:first-child hover ("Cancel")]
    ```
    
    And as of today (or gjs >= 1.67.3) that's reported as an error:
    ```
    JS ERROR: Error: Argument timestamp: value is out of range for uint32
    popModal@resource:///org/gnome/shell/ui/main.js:638:12
    popModal@resource:///org/gnome/shell/ui/modalDialog.js:206:14
    close@resource:///org/gnome/shell/ui/modalDialog.js:179:14
    ```
    and so you can't Cancel the dialog anymore.
    
    Make sure `ModalDialog.close()` receives an `undefined` timestamp it
    knows how to handle.
