fix(entrypoint): arm cron worker via self-ping after boot

instrumentationHook is disabled in the standalone build, so node-cron only
arms on POST /api/worker/ping. Without a self-ping, a fresh container or
restart runs zero ingest passes (worker silently never armed) — exactly
what happened on the :8 deploy. Adds the same self-ping block as
technews/finance entrypoints (identical).
