tanshu bf824cae26 Wait on the container's own health, not the host's DNS
The app's health check ran on the target host against the container name, which
only resolves inside the Docker network, so the wait could never succeed. Poll
the image's HEALTHCHECK instead and fail with a readable message. Also pin
site.env to the app user when it exists, and say how to install the provisioning
script on the server.
