It should be possible to upload a zip file of pdfs

Description

This will likely change somewhat in the future, but the process should stay the same:
in the admin interface for pdf resources, I want to be able to upload a zip file that contains:
multiple pdfs
a file that contains some metadata about the files (this is the part that will likely change)
Hopper should upload each file to the KB server
in the future we might send the metadata along with the file as well
Hopper should use the metadata from the file to fill in metadata fields for pdf resources (right now that would be just title)
let’s make the metadata file a csv file for now with two columns: filename, title
we assume the pdfs are all next to the metadata file

HOP-60

Anything else the reviewer needs to know?

The KB MCP Is still timing out when we upload a zip, thats why I created a draft pr.

Does this Pull request depend on any other?
