Add HEALTHCHECK to Dockerfile.base as well.

Issue #1430 requires HEALTHCHECK in both Dockerfile and Dockerfile.base. The change currently only addresses Dockerfile. Add the same HEALTHCHECK directive to Dockerfile.base at the appropriate location.

In `@Dockerfile` around lines 174 - 179, The Dockerfile change added a HEALTHCHECK
block (HEALTHCHECK --interval=30s --timeout=5s --retries=3 \ CMD curl -sf
http://127.0.0.1:18789/health || exit 1) but the same directive must also be
added to Dockerfile.base; open Dockerfile.base and add an identical HEALTHCHECK
directive (same interval, timeout, retries and CMD curl -sf
http://127.0.0.1:18789/health || exit 1) at the analogous location where health
checks are defined in Dockerfile (near the end or after the service start/EXPOSE
steps) so both images include the same container health probe.
