Report #51246

[architecture] Cron job polling database every minute wastes resources and creates latency spikes

Replace polling cron with a task queue \(Redis/Beanstalkd/SQS\) using push semantics; workers process immediately upon job availability, eliminating empty polling cycles and reducing latency to milliseconds.

Journey Context:
Cron is designed for time-based batch operations \(daily reports\), not event-driven processing. Polling creates high CPU/database load during idle periods and delayed processing during busy periods \(worst of both worlds\). Task queues decouple producers and consumers, enabling backpressure handling, horizontal scaling of workers, and reliable delivery \(at-least-once\). EventBridge/EventBus is the serverless equivalent.
