Fix test for Blob to File conversion

Browse Source 
The Response.blob() method in JavaScript returns a Blob, not a File.
This means that file-specific metadata like `name` and `lastModified` is
lost. The tests were updated to reflect this by manually constructing a
File object from the Blob, mimicking how client code would handle this
conversion. The MIME type is now correctly preserved from the response
headers when creating the File.
