chore: enable volume extra test

[mckornfield]

• Also fix nss test

Summary by CodeRabbit

• New Features
  • Added E2E Helm configuration for Kubernetes/Volcano-style job executors to attach an extra PVC-backed volume mounted at /mnt/additional_storage.
  • Enabled an additional-volume CPU executor profile across the E2E inference gateway and minikube/kind environments.
• Tests
  • Updated the additional-volume job E2E test to run based on whether the required /mnt/additional_storage mount is available.
  • Improved Safe Synthesizer E2E model-fileset setup by loading the setup logic in-process and validating the expected fileset count.
  • Adjusted the online evaluator mock model flow to control virtual-model auto-provisioning behavior explicitly.

📝 Walkthrough

Walkthrough

E2E Kubernetes job profiles now mount a PVC-backed volume at /mnt/additional_storage, and the additional-volume test selects or skips the profile based on service configuration. Safe Synthesizer setup runs in-process, while evaluator mock-model provisioning uses explicit virtual-model controls.

Changes

E2E job storage

Layer / File(s)	Summary
PVC-backed job storage configuration e2e/k8s/values/*.yaml	Kubernetes job executor profiles define nmp-additional-volume, its PVC wiring, and the /mnt/additional_storage mount.
Conditional additional-volume validation e2e/test_jobs.py	The test receives RunningServices, selects the configured profile for both job steps, and skips when the required mount is unavailable.

Safe Synthesizer fileset setup

Layer / File(s)	Summary
In-process model-fileset registration e2e/test_safe_synthesizer.py	The fixture dynamically loads setup_model_filesets.py, invokes create_filesets, validates the created-fileset count, and removes subprocess-specific handling.

Evaluator mock-model provisioning

Layer / File(s)	Summary
Explicit virtual-model provisioning controls e2e/test_evaluator_plugin.py	Mock provider creation and passthrough virtual-model setup explicitly disable auto-provisioning and mark the resulting model as non-autoprovisioned.
