fix(agent): correct AGENT_MODEL_CONFIG versions for gpt-5.1+ [hotfix/v5.961]

[rllyy97]

Commit Type

• fix - Bug fix

Risk Level

• Low - Minor changes, limited scope

What & Why

Cherry-pick of #9321 (46488af) onto hotfix/v5.961. Corrects the version strings in AGENT_MODEL_CONFIG for existing gpt-5.1+ entries to match the official Azure OpenAI / Foundry model catalog. Stale versions (e.g. gpt-5.4-nano was 2025-08-01) caused DeploymentModelNotSupported 400 errors when creating Cognitive Services deployments. No models added or removed.

Impact of Change

• Users: Agent model deployments (gpt-5.1+) request the correct model versions; resolves 400 deployment failures.
• Developers: No API/shape changes; config keys unchanged.
• System: Data-only change to a config map.

Test Plan

• Manual testing completed
• Tested in: versions cross-checked against the official Microsoft Learn "Foundry Models sold by Azure" catalog; to be validated in portal release/20260514.
