# ProxMenux Monitor - Shutdown Notification Script
# This script is called by systemd ExecStop before the service terminates.
# It sends a shutdown/reboot notification via the running Flask server.
# It sends a shutdown/reboot notification ONLY when the system is actually
# shutting down or rebooting, NOT when the service is manually stopped.
