Restructure scripts into dev/ and prod/ for the devcontainer

- scripts/prod: entrypoint, db-setup and schema.sql shipped in the image
- scripts/dev: seed/clear db, psql and cleanup, run natively in the
  devcontainer instead of via docker-compose
- move setup.cfg to the repo root so linters pick it up
- Makefile targets run directly in the devcontainer
