[DevOps]: Update ingestion script and cronjob to link diagnostics

### Task Details

After #269, #169, and #281 are complete, update the cron job at each site to run the diagnostic scanner Python module. The scanner shares several environment variables with the ingestion module but requires additional configuration.

### Steps to Complete

TBD

### Additional Notes

_No response_

Start by reviewing issues #269, #169, and #281, since this work depends on their completion. Then inspect the per-site cron job, the ingestion module, and the diagnostic scanner Python module to identify shared and additional environment variables. Done means each site’s cron job runs the diagnostic scanner with the required configuration and links its diagnostics to ingestion.
