Anonymize Should Wait for Job to Finish before Responding

**Is your feature request related to a problem? Please describe.**

Currently, the job that Jeeves creates gets created but we don't check that it completes successfully

**Describe the solution you'd like**
There Should be a check to make sure that the job has completed, and then send to the slack channel that the API has been anonymized

Locate the API path that starts the anonymization job and the existing Slack notification flow. Trace how job completion and failure are represented; done means the response waits for a successful job and the Slack channel is notified only after anonymization succeeds.
