📄 Description
Azure offers two URL formats: the legacy deployment-based format (/openai/deployments/{model}/...) and the newer v1 format (/openai/v1/...) where the model stays in the payload body and no api-version query parameter is needed.
Previously, the code always ran convert_to_azure_payload which rewrites the URL to the deployment format, causing 404 errors for users with v1-style base URLs. Now, when the base URL contains '/openai/v1', we skip deployment URL construction and route directly.
Applied consistently across all three Azure routing paths: generate_chat_completion, /responses proxy, and generic proxy.
