MainCode/adalm1000_logger.py aktualisiert

Test phase display issue: When continuous mode is disabled and the discharge voltage is already below cutoff, the phase still shows "Discharge" instead of switching to "Idle".

    Graph update issue: The plot sometimes fails to update when starting a new test series.
