Add Phase-3 plan: beautiful YunoHost-style results (levels + image comment + dashboard)

Phase 3 (after Phase-2 DONE, manual transition): compute a per-run quality LEVEL, post an
image-forward Gitea PR comment in the YunoHost shape (marker + status/level badge + a
rendered summary card containing a real app screenshot, linking to the run), and polish the
overview dashboard to a ci-apps.yunohost.org look/feel with per-recipe level badges +
screenshots. Reuses the Phase-1 dashboard/bridge/Playwright; presentation never changes the
verdict; no secrets in any artifact; cosmetics never block the pipeline. Linked from README.
