Add shutdown timer monitor service to prevent disabling
- Remove 'disable' option from setup_midnight_shutdown.sh - Add shutdown-timer-monitor.sh that watches the timer every 30s - Re-enables timer automatically if someone tries to disable it - Monitor service installed alongside the timer - Makes it significantly harder to bypass the shutdown schedule - Similar pattern to hosts-file-monitor.service
