CI training jobs run as GitLab runner pods, not K8s Jobs, so the
kube_job_status_active query always returned 0. Switch to
foxhunt_training_active_workers which is emitted by all training
binaries regardless of deployment method.

- DQN/PPO trainers now record epoch, loss, val_loss, batch/s every epoch
- CI training jobs get Prometheus scrape annotations via runner overrides
- Allow Prometheus (foxhunt namespace) to scrape foxhunt-ci pods
- Skip no-model metrics in monitoring service session grouping

Prometheus client queries training/hyperopt/GPU/K8s metrics, gRPC service
exposes unary + server-streaming RPCs, 4 unit tests, zero clippy warnings.
