Ensure WMI monitors support brightness control

Browse Source 
Added a condition in `PowerDisplayViewModel` to ensure that monitors using the "WMI" communication method are always marked as supporting brightness control. This is achieved by explicitly setting `monitor.SupportsBrightness` to `true` for WMI monitors, as brightness is controlled through the Windows WMI interface. Updated comments to clarify this behavior, improving compatibility and accuracy for WMI-based monitors.
