Remove nginx from docker compose

Nginx was added to the IBF setup because the vision was that there would be many IBF instances. However, this is not the case anymore. We should move the nginx config outside the docker-compose setup and make it a part of the host machine (similar to the webhook). For development, we can keep a nginx image in the override file without the letsencrypt and certbot dependencies.
