+Show GPU utilization and GPU memory utilization charts in the log/span side
+panel Infrastructure section when `hw.gpu.*` metrics (OTel hardware semconv)
+exist for the correlated host/node. Multiple GPUs on a host render as separate
+series grouped by `hw.id`. The section is fully hidden when no GPU metrics are
+present and partially rendered when only one metric is available.
