Effective Flags

Effective funnel flag states + registered scheduler jobs (cron-token guarded).

scheduler_jobs reflects whichever uvicorn worker answered this request (each worker runs its own APScheduler). Every worker registers the same job list from the same env, so this is all-or-nothing detection — it catches OUTREACH_ENABLED=false (no jobs anywhere), not a single worker whose scheduler died. pid tells repeated calls apart.
