…ve calls LiteLLM silently fell back to application/octet-stream when file_uri MIME type could not be determined, using only a debug log that was easy to miss. Upgrade to warning level so developers notice the fallback. Also fix _content_to_message_param() to propagate the model parameter in recursive calls for mixed function_response + content parts, which caused incorrect provider detection on Vertex AI / Anthropic. Fixes google#5184
