"Starting worker thread" leaks node credentials in logs

- Say we want to post our logs for debugging to someone, then we have to make sure that we don't post the line starting with:

```
@attestate/extraction-worker:worker Starting as worker thread with queue options: "

```
Because it would include secret credentials. So for the console we should "censor" them.

Search the crawler for the log line beginning "@attestate/extraction-worker:worker Starting as worker thread with queue options:" and trace how its queue options are formatted. Verify the console output no longer exposes node credentials while retaining safe worker-start information.
