Restore and Improve Cron Job for Scheduled Drawings

[shashilo]

Currently, the cron job that automatically runs drawings on user-selected days is disabled. This feature needs to be restored and/or redesigned so users receive drawings precisely when expected.

Additional Context

• Investigate why the cron job was disabled, provide documentation of reason and impact.
• Solutions may include using native OS cron, external schedulers, or serverless functions (AWS Lambda, GitHub Actions, etc.).
• Reference documentation:
  • Node.js cron module
  • GitHub Actions Scheduling
  • AWS Lambda Scheduled Events
• Confirm user-selected day logic is honored and robust against failures. Allow for manual re-run if required.

Acceptance Criteria

• Automated drawing runs reliably on the day chosen by user.
• Failure/disablement reason is documented.
• Solution is robust and maintainable.
