podman builds an OCI image by default and drops Docker's HEALTHCHECK instruction,
so the container had no health at all and the play failed waiting for one. The
check is now declared on the docker_container task - node is in the image and the
exec form needs no shell quoting - which is both what operators see in docker ps
and what an orchestrator would use.
The wait still asks the app directly rather than reading State.Health, because a
container that already exists is only rebuilt when the image tag changes or when
-e recreate_container=true is passed, and a wait must not depend on a container
attribute an existing one may not have.
