fix Swagger validation

Toggling the definition between "Archival" and "Directory in the Swagger UI throws 502 Bad Gateways. But, loading the URL to the swagger.json files directly works just fine...

Well, the Directory one currently works. Archival is temporarily disabled. Maybe because Archival API is broken, toggling to Archival and then back to Directory is unrecoverable... hmm...

The Swagger spec badges on the GitHub README are also reporting errors. Possibly related.

Bad gateway issue fixed-ish by getting the Archival API back up and running (skipping job enqueueing for now).

But, spec validation is still failing.
