chore(docker): add compose override for local server development

Add a docker-compose override file that stubs out the Cadence server
container while keeping infrastructure dependencies (Cassandra, Kafka,
Elasticsearch, Prometheus, Grafana) running in Docker. This enables
running and debugging the server natively from the local repository
against real dockerized dependencies.

+#
+# The cadence service is replaced with a no-op container so that only the
+# infrastructure services start. Kafka advertises on 127.0.0.1 so the
+# host-running server can reach it, and cadence-web points back to the host.
