Fix Options page not showing correct ConfirmCloseConnection value

- Add VisibleChanged event handler to ConnectionsPage to reload settings when page becomes visible
- Save settings immediately when user checks "Don't show this message again" checkbox during connection close
- Ensures Options dialog always displays current setting value, even if changed outside the dialog
