feat(portals): serve each portal with Caddy instead of nginx (refs #166)

nginx resolves a variable `proxy_pass` upstream itself, using only the `resolver` directive and never the search domains in /etc/resolv.conf. That cost two workarounds in one script: rewriting the resolver address for rootless podman (Docker's 127.0.0.11 is wrong there), and injecting a full FQDN so the bare `bff` name could resolve on Kubernetes at all. Caddy dials its upstream per request through the system resolver, which reads nameserver *and* search domains, so `reverse_proxy bff:8080` resolves on every engine with no per-engine configuration — and it still starts before the BFF exists and picks up its restarts. Both workarounds are deleted with the script. Routing uses mutually-exclusive `handle` blocks, not a bare `try_files`: Caddy sorts rewrites *before* reverse_proxy, so a top-level SPA fallback would rewrite every API path to /index.html before the proxy saw it.
