Add a color accent or an animation for the system tray icon when the connection is active

[GregFedy]

It is impossible to determine if the connection is active by the icon in the system tray (Windows 11).

You have to click on the right mouse button to see a check mark indicating that the connection is active

For example, when the connection is active, the icon should change color from white to orange (as the main color of the application)
