Prometheus was configured to scrape pods via prometheus.io/scrape
annotations, but all services and training jobs used gitlab.com/
prefix from legacy GitLab-managed Prometheus — causing Prometheus
to never discover any foxhunt pods. This resulted in stale/missing
metrics on the Grafana training dashboard.
12 files updated across services/, gpu-overlays/, training/, and
monitoring/ (node-exporter, dcgm-exporter cleanup).
