Add host maintenance mode and NUT/Tailscale helpers
prox-maintenance-mode.sh saves and clears onboot/startup across all VMs and CTs so a host can be rebooted without guests coming back up, then restores the saved state. Supports --status and --dry-run. nut-udev-restart.sh restarts the NUT UPS driver on a USB re-enumeration event. tailscale-optimize-router.sh applies the recommended UDP GRO forwarding offloads for subnet routers.
