Azure OpenAI endpoints were not recognized by shouldForceResponsesStore(),
causing store=false to be sent with all Azure Responses API requests.
This broke multi-turn conversations because previous_response_id referenced
responses that Azure never stored.
Add "azure-openai-responses" to the provider whitelist and
*.openai.azure.com to the URL check in isDirectOpenAIBaseUrl().
Fixes#27497
