Residue from the Caddy HA -> Traefik migration (Caddy LXCs destroyed in
PR #70):
- install-error-page.yml, install-gitea-proxy.yml: both target the
destroyed host caddy.srv.renner.uno (the gitea-proxy play also wrote a
Caddyfile reverse_proxy block + cloudflare import; gitea is now served
by a Traefik Ingress in kubernetes/apps/gitea).
- grafana-observability: drop the caddy-overview dashboard (monitored
caddy_http_* metrics from the dead Caddy HA) and its two deploy/cleanup
loop entries.
Note: a previously-provisioned Network/caddy-overview.json may still
linger in the live Grafana until the dashboards are re-synced or it's
removed in the UI; it just shows no data.
