Code Review
This pull request adds support for chat_template_kwargs in the OpenAI Responses API, enabling the passing of keyword arguments to the chat template renderer through both request parameters and server-level defaults. Feedback indicates that the default_chat_template_kwargs are not being propagated to the preprocess_chat method in the rendering logic, which causes server-level defaults to be ignored.
