fix(genebean): restart cage-tty1 on config changes

Upstream's cage module sets restartIfChanged = false, presumably to
avoid yanking an interactive desktop session out from under someone
mid `nixos-rebuild switch`. That caution doesn't apply to a kiosk -
confirmed on hardware (kiosk-entryway) that without this override, a
config change (e.g. a new dashboard URL) requires a manual `systemctl
restart cage-tty1` or a reboot to actually take effect, since the
switch itself silently leaves the old chromium/cage instance running.
