build: stamp the version in the stage that ships it

The release workflow has never published. Every run since v1.1.19 built
cleanly and then died on its own smoke gate:

    image stamps <unset> but is published as v1.1.23

The gate was right. GIT_TAG and GIT_COMMIT_SHA were declared as ARG/ENV
only in the `builder` stage, and ENV does not cross a stage boundary, so
they reached the compiled bundle and never the runtime image. The footer
resolves at container start, not at build time — make_envs_script.sh
iterates the live process environment into window.__envs and
configs/app/ui.ts reads frontendVersion from there — so with nothing set
in the final stage, every image ever published reported no version.
`crane config ghcr.io/luxfi/explore:v1.1.23` confirms it: no
NEXT_PUBLIC_GIT_TAG in the config at all, and the deployed ConfigMaps do
not supply one either.

Declare both in the runner stage, after the copies so a new commit
invalidates only the ENV layer.
