Restore right-click "Retrieve Live Data" option on map devices

NetBrain currently does not provide a right-click option on map devices to directly retrieve live data; users must navigate through multiple additional steps to achieve the same result. This enhancement would reinstate a direct right-click "Retrieve Live Data" action from the map context menu for individual devices. Restoring this streamlined workflow would improve efficiency for users who frequently need quick access to current device data without extra navigation.
