ci: enable PKG_CACHE via a TLS probe that falls back to upstream; host repo tool

- build-push.yaml: Build-and-Push, Build-FPM-Images, Build-Shared-httpd
  and Build-Shared-OLS probe https://192.168.1.40 and :5000 with the
  pinned pkg-cache CA (5 s timeouts). When the cache answers they pass
  PKG_CACHE and configure the BuildKit Docker Hub mirror (ca=). When it
  doesn't, they build from upstream exactly as before and emit a warning.
  Fallback measured from the runner bridge: refused <1 s, silent drop 10 s.
- scripts/host/pkgcache-host-repos.sh: apply/revert/status for WHP hosts.
  Each rewritten repo uses baseurl=<cache> <origin> as the real fallback;
  mirrorlist/metalink stay commented because measured dnf ignores baseurl
  when they are present. Keeps gpgcheck=1 / repo_gpgcheck=1 and backs up
  every file. Tested on 192.168.1.148, including cache-down and
  silent-drop fallback.
- docs: runner firewall rule (applied), measured fallback results.
