feat(sambanova): update model YAMLs [bot]

[models-bot]

Auto-generated by poc-agent for provider sambanova.

---

Note

Low Risk
Single metadata field on a provider model config; no application or routing logic changes.

Overview
Adds a features section to gemma-3-27b-it.yaml listing system_messages, so this SambaNova model is marked as supporting system-role chat messages like other provider chat YAMLs.

No pricing, limits, modalities, or runtime behavior change—metadata only.

Gateway test setup failed for sambanova

The test job aborted before any tests ran. Error:

Failed to apply provider-account/sambanova 'test-v2-sambanova': {"statusCode":401,"message":"Invalid or expired token"}

This is usually a transient infra issue (catalogue build, TrueFoundry API, GitHub archive). Try /test-models again, or check the job logs.
