Subject: [PATCH] fix: add fallback default for HOST_DATA_DIR in docker-compose

If HOST_DATA_DIR is unset, Docker Compose mounts an empty path,
creating an anonymous volume that is difficult to locate and easy to
accidentally prune. Add a Compose-level fallback of ./data so that
chain data is always persisted to a predictable local directory,
even when the env variable is missing.
