[openclaw,tor-proxy] Opt task-webhook + torrserver out of external monitoring

Adds `external_monitor = false` to the ingress_factory calls for
task-webhook and torrserver so the `external-monitor-sync` CronJob
stops auto-creating `[External] <name>` monitors for them. Both
services remain deployed and reachable; only the Uptime Kuma monitors
are dropped.
