🔄 Auto Payment Process

Workflow

1. Upon successful money transfer, if auto pay is enabled, a scheduled task is created in the scheduler_service.
2. Celery Beat periodically checks and triggers payments as per the schedule.
3. Payments are processed securely, ensuring compliance with user preferences and transaction records are updated in real-time.
