feat(reports): static site at report.ci.commoninternet.net for the weekly Recipe Report

nginx:alpine swarm service serving /var/lib/cc-ci-reports behind traefik
(Host(report.ci.commoninternet.net) + wildcard TLS), deployed by a reconcile
oneshot mirroring dashboard.nix. The /recipe-report skill writes the weekly
HTML pages there; nginx serves them live. report.ci.* already resolves
(wildcard *.ci DNS) and is covered by the wildcard cert.
