Replaces the vendored Go exporter with two pre-built upstream images: - quay.io/prometheuscommunity/json-exporter:v0.7.0 maps the gateway JSON into prometheus metrics via JSONPath. The G4AR keys signal blocks as "5g" / "4g" (digit-prefixed), which the k8s client-go JSONPath dialect only reaches via bracket-with-single-quote notation. - nginxinc/nginx-unprivileged:1.27-alpine-slim sidecar rewrites GET /metrics → GET /probe?module=tmhi&target=http://192.168.12.1/... so the existing kubernetes-services scrape job picks it up over the apiserver proxy with no Prometheus-side config changes. Avoiding caddy here: its binary carries cap_net_bind_service file caps, which the kernel refuses to exec under no_new_privs as a non-root user. Dashboard "Gateway up" panel now reads up{service="tmobile-exporter"} (Prometheus's built-in scrape-success gauge) since json_exporter's /probe endpoint does not emit probe_success.
