Standard K8s NetworkPolicy ipBlock rules don't work under Cilium for
the API server — the except clause on 192.168.1.0/24 blocks the
post-DNAT destination even when a separate rule re-allows the subnet.
Cilium's native kube-apiserver entity tracks API server endpoints
regardless of ClusterIP vs node-IP routing.
Replaces: ipBlock 192.168.1.0/24:6443 (broken under Cilium)
With: CiliumNetworkPolicy toEntities: kube-apiserver (works)
CI runner needs kubectl access to create Tekton PipelineRuns for integration testing.
## Root Cause
The runner egress NetworkPolicy blocks `192.168.1.0/24` (LAN). The K8s API server runs on control-plane nodes in that subnet (`192.168.1.166:6443`). kubectl from inside the DinD container times out.
## Fix
Allow TCP port 6443 to `192.168.1.0/24` — scoped to control-plane API server only.
## Required By
homelab-frontend PR #25 (Tekton integration testing) — CI creates PipelineRuns via kubectl.

- Runner egress: allow 192.168.1.160/32:443. forgejo.riotpiao.com resolves to
the ingress LB, inside the 192.168.1.0/24 block the NetworkPolicy denies, so
docker push hung until timeout.
- dind CA: also mount homelab-ca at /etc/docker/certs.d/forgejo.riotpiao.com/,
the path dockerd actually reads for per-registry trust.
- Pull secret: dockerconfigjson for the api namespace; /v2/ answers 401.
- AppProject: allow the Forgejo repo as a source for api-gw.
