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.
