feat(monitoring): Intel iGPU dashboard

Grafana dashboard for the gpumon_* series from intel-gpu-exporter:
current Render/3D busy, GPU power and GT frequency per node as stat
tiles, then one time series per engine (Render/3D, Video, VideoEnhance,
Blitter) with node as the series, GT frequency, GPU and package power,
and memory-controller read/write bandwidth.

Node colours are fixed per node across every panel — blue, orange, aqua
for k8s-1/2/3 — rather than assigned by series order, so a node keeps
its colour whatever the $node filter shows. The trio validates for
colour-vision deficiency and normal vision on both Grafana themes
(worst all-pairs ΔE 9.4 / 20.9). Reads and writes share one axis and
differ by dash, not hue. One axis per panel throughout.

gpumon_clients_count is deliberately absent: per-client attribution
needs hostPID, which the exporter does not have, so it would read 0
forever and imply an idle GPU.

+"""netbird-proxy-services: reconcile NetBird reverse-proxy services from Ingresses.
+
+Source of truth: every Ingress carrying the public label (dns.renner.uno/public).
+For each host on such an Ingress the NetBird management gets one reverse-proxy
+service in TLS-passthrough mode on :443, targeting Traefik's ClusterIP through a
+subnet resource that covers the cluster's service CIDR. SNI and Host reach
+Traefik untouched, the proxy terminates nothing, and no domain resource is
+involved -- the routing peers stay ordinary IP routers. The target sends a
+PROXY protocol v2 header so Traefik (and CrowdSec behind its access log) sees
+the WAN client address instead of the routing peer's pod IP.
+
+Ownership is derived from NetBird itself, not from local state: a service is
+managed iff its mode is "tls" and its target is this controller's subnet
+resource. Services that do not match (the hand-made HTTP/domain ones) are never
+touched; a desired host held by such a service is reported and skipped until
+that service is removed by hand.
+
+Credentials: the NetBird PAT is read from OpenBao on every pass through the
+Kubernetes auth role, exactly like the setup-key rotator; it never lands in a
+Kubernetes Secret or in a log line.
