Increase Node.js heap limit for webpack production build

The webpack build with TerserPlugin and CssMinimizerPlugin runs
out of memory in constrained Docker build environments (~986MB heap
used before OOM). Setting NODE_OPTIONS inline for only this RUN step
raises the limit to 2GB without affecting other processes.
