Make Dockerfile.dev built containers a drop-in for production images. (#682)

Without this change, you can't easily swap a dev container for a production
(release) container because there are fundamental differences.  Allowing it
to be a drop-in replacement makes it easier to test on real fabrics.

- Use the same (environment variable) mechanism for configuring the default
  data path for consistent overrides.
- Use the same uid (1000) so permissions match.
- Add --ignore-scripts to npm ci to prevent build lifecycle scripts from
  running before source code is copied.
