In docker-compose, services can reference each other by name (e.g., 'db:5432').
In Kubernetes, when multiple containers are in the same pod (sidecars), they
share the same network namespace and must use 'localhost' instead.

This fix adds translate_sidecar_service_names() which replaces docker-compose
service name references with 'localhost' in environment variable values for
containers that share the same pod.

Fixes issue where multi-container pods fail because one container tries to
connect to a sibling using the compose service name instead of localhost.
