M8/D7: results dashboard — overview + SVG badges at ci.commoninternet.net

Stdlib HTTP service (like the bridge): polls the Drone API for recipe-CI builds (event=custom),
groups latest-run-per-recipe, renders a YunoHost-CI-like overview table with pass/fail/running
badges + links to the canonical Drone run, plus /badge/<recipe>.svg. Nix-built OCI image, swarm
service on proxy, traefik Host(ci.commoninternet.net) (the bridge's /hook rule stays higher
priority by length). Reuses the Drone token (read-only). Reconcile oneshot like bridge/drone.
