local development CORS issue

[PeterHindes]

When we're using this Docker Compose File in production we also add a caddy config that overwrites the Coors headers to allow the front end to request things like admin theme and admin plug-ins from the backend. But in development mode, this caddy configuration has been left out for some reason.

I propose we either add the Caddy configuration, or we modify the Synbiohub 1 backend image to automatically have the CORS headers, which would probably be the proper thing to do.

I think it would also be intelligent to add the chorus configuration to a doctor-compose-prod.yml file.
