fix: omit GPT-6 Astra from the Azure known-models catalog on 2.37

The fantasy pin on release/2.37 predates gpt-6-astra, and the Azure provider exposes no hook to force Responses, so an Azure Astra model config would speak Chat Completions while Astra's function calling is Responses-only. main added the Azure entry after bumping fantasy (#29230), which the backport does not carry. TestCuratedAstraUsesResponses guards the curation against reintroducing an Astra entry whose resolved transport is not Responses.
