fix(iso): pet hardware watchdog via systemd RuntimeWatchdogSec=30s

Without a keepalive the kernel watchdog timer expires and reboots
the host mid-audit. Configuring RuntimeWatchdogSec lets systemd PID 1
reset /dev/watchdog every 30 s — well within the typical 60 s timeout.

# Pet the hardware watchdog every 30s so the host doesn't reboot mid-audit.
# Kernel watchdog timeout is typically 60s; 30s gives a safe 2× margin.
