🐛(project) run production image locally with docker-compose

The local deployment of the Production image through docker-compose was
failing due to issues in the Django configurations, influenced by Joanie.

The bug stemmed from a dependency on a development-specific package
(drf-spectacular-sidecar) while attempting to run the application in
production mode.

Changes Made:
- Introduced new Django settings for local demo environments.
- Uncommented the nginx configuration to address the production image
  deployment issues.
