fix(infra): portal nginx resolver works on podman too, not just Docker
The portal reverse proxies hardcoded Docker's embedded DNS (resolver 127.0.0.11); on rootless

podman the DNS is network-specific (aardvark), so every proxied BFF call 502'd. Add an

/docker-entrypoint.d hook that rewrites the resolver from the container's /etc/resolv.conf at

startup — a no-op on Docker (nameserver IS 127.0.0.11), correct on podman. Verified: the built

image rewrites to 10.89.0.1 and /behandel/werkbak proxies to the BFF (401, not 502).
