HuggingFaceEndpointEmbeddings missing bill_to/additional_headers support
The replacement HuggingFaceEndpointEmbeddings class in langchain-huggingface does not expose parameters to pass billing headers (e.g., X-HF-Bill-To) or custom headers to the underlying InferenceClient, causing 401 Unauthorized errors for users relying on organization-level billing. This capability was available in the deprecated HuggingFaceInferenceAPIEmbeddings.
