monitor.sh: worker check accepts autoscaler (static worker retired)

Since the autoscaler takeover (static codex-cloud-worker stopped at
2026-10-26 07:02:55, disabled by design), the monitor's worker check
(systemctl is-active codex-cloud-worker) has failed every 5 minutes
while the real workers were healthy (health worker_ok kept passing,
GET /workers shows live autoscale-1 + host-1). A monitor that always
fails masks real failures. Fix: pass if either codex-autoscaler or
codex-cloud-worker is active, covering both deployment modes; the
health check still covers worker heartbeat freshness.
