Cache PostGIS Docker image in CI
Replace service container with manual docker run + cached image tar.
Service containers pull the image before steps run (uncacheable).
Manual approach: cache the image as a tar, load on cache hit.

PostGIS image is ~400MB — first run pulls and saves, subsequent
runs load from cache in ~2s instead of ~19s.
