Fix unnecessary full file download when checking URL authorization

[qiacheng]

Found a bug when running comfy-cli model download --url https://huggingface.co/Comfy-Org/flux1-schnell/resolve/main/flux1-schnell-fp8.safetensors

it will fully download the model first before going into download_file(url, local_filepath, headers) .

Model gets downloaded twice, first time was to verify hf repo access, and second time was the actual download.

response = requests.get(url, headers=headers, allow_redirects=True, stream=True)

simple fix is to add stream=True to requests.get in check_unauthorized() to prevent full file download
