Google's Gemini API rejects requests with HTTP 400 "Multiple authentication credentials received" when the OpenAI SDK injects both an Authorization: Bearer header and the x-goog-api-key header. Route the API key through x-goog-api-key and set a placeholder api_key to suppress the SDK's automatic Bearer header. Closes NousResearch#7893
