Add AppIndicator test and support for virtual desktops

Introduces a Python script to test AppIndicator/Ayatana integration in MATE and XFCE environments. Updates setup scripts to install required dependencies, start the indicator service where supported, and run the test script with screenshot capture. Adds a requirements.txt for Python dependencies.
