The 13 `X-Frame-Options DENY if acl_<host>` rules in `fe_https` have never fired:
their ACLs use `req.hdr(host)`, a request-direction fetch that is invalid in a
response ruleset, so HAProxy rejects them at config-check time. Carried over
verbatim from the Puppet LXD config during the k8s move.
- Remove the 13 dead `http-response set-header X-Frame-Options` rules.
- Remove the 15 now-orphaned `acl acl_*` definition lines.
Not switching the header on: it has never been live, and Grafana/Gitea send their
own. `haproxy -c` warnings drop 33 -> 20; the two working response headers stay.
