Add extra_headers field to OpenAIModelConfiguration TypedDict and merge it into per-call extra_headers in construct_prompty_model_config. This enables prompty-based evaluators to send custom HTTP headers (e.g., X-ModelType) required by OpenAI-compatible endpoints that need custom routing headers.

Summary
Adds an
extra_headersfield toOpenAIModelConfigurationTypedDict, enabling prompty-based evaluators to send custom HTTP headers on every LLM call. This unblocks integration with OpenAI-compatible endpoints that require custom routing headers.Changes
_model_configurations.py: Addextra_headers: NotRequired[Dict[str, str]]toOpenAIModelConfiguration_common/utils.py: Mergeextra_headersfrom model config into per-callextra_headersinconstruct_prompty_model_config()How it works
Customer headers are merged into the
extra_headersparameter onchat.completions.create(), which the OpenAI SDK merges after default headers - allowing override of any header includingAuthorization.
