The hint under the app page's environment variable editor asked for a
container restart. Environment variables are set when a container is
created, and upaas's restart stops and starts the same container, so it
keeps the old values; deploy and rollback each create a new container.
The hint now says so in one sentence, styled with badge-warning, the
warning style the page already uses: its old text-amber-600 class is not
in the built stylesheet. A handler test renders the app page and checks
the hint.
