Subject: [PATCH 2/2] address Copilot review: add gateway healthcheck, use
 condition: service_healthy

depends_on only sequenced container start, not readiness -- the frontend could
still race the gateway before it was actually accepting connections. Added a
healthcheck to datamate-gateway (curl against its own port; there's no Spring
Boot Actuator on this image per backend/api-gateway/pom.xml, so a plain
"did we get any HTTP response" check is the honest signal available) and
switched datamate-frontend's dependency on it to condition: service_healthy.
backend/backend-python keep condition: service_started (unchanged behavior).
