HA live video from the cluster Frigate hangs/fails because the only path
to Frigate is the Traefik HTTP(S) ingress (frigate-lan -> 10.0.20.203),
which cannot carry RTSP or WebRTC. The container already listens on
8554+8555 but only RTSP had a Service (NodePort), and WebRTC (8555) was
never exposed. Convert frigate-rtsp to a LoadBalancer on a dedicated MetalLB
IP (.204, ETP=Local, pod pinned to the GPU node) carrying RTSP 8554 +
WebRTC 8555 (TCP+UDP), giving HA Sofia + LAN browsers a stable cross-VLAN
endpoint for native HLS/WebRTC live (parity with the Hikvision NVR).
Companion non-Terraform steps are in the PR body.
