fix: authorize upload error on create job endpoint

[davidgamez]

Summary:

When utilizing the feed URL https://www.maricopa-az.gov/home/showpublisheddocument/6491/638307291320330000, an "Error authorizing upload" occurs. Upon attempting to save the file to GCP for validation, it was observed that the HTTP request lacked a user-agent, leading to rejection by the producer in this specific instance.

This is a missing fix from #1633.
Fixes #1632

Using the Channels output stream reduces the memory footprint by avoiding loading the full file in memory.
