Make the HTTP vision provider's configuration independent of the main chat model: the API key default moves from DEEPSEEK_API_KEY to IMAGE_RECOGNITION_API_KEY, and the URL and model get image-recognition-specific defaults (Aliyun DashScope compatible-mode and qwen3-vl-flash) instead of the chat model's deepseek-v4-flash. The provider fails loud when no model is configured. Co-Authored-By: Claude <noreply@anthropic.com>
