Add GPU node taint tolerations and enhance GPU memory exporter

Add nvidia.com/gpu toleration to all GPU workloads (frigate, ollama)
to support NoSchedule taint on GPU nodes. Update nvidia operator
helm values with daemonset tolerations. Enhance GPU pod memory
exporter with Kubernetes API integration to resolve container IDs
to pod names/namespaces, adding RBAC resources for API access.
