[Issue]: Only Treasury Files Filter on Uploads table

[ClaireValdivia]

Why is this issue important?

We want to provide an easy way for partners to filter the Uploads table by files that are included in a treasury report to support with troubleshooting and report finalization.

Current State

There is no way to easily determine which files are used in a treasury report

Expected State

On the Uploads page, add checkbox to the left of the "Reset Filters" button that shows a checkbox next to text "Only Treasury Files"
The checkbox should default as unchecked with all files displaying
If the checkbox is clicked and checked on, the uploads table should only display files used in the treasury report (i.e. the most recent valid file for each project/agency/EC Code combination
If the checkbox is clicked again and is empty, the table should display with all uploads

This is unrelated to the checkbox, but partners have also requested that the uploads table be defaults to show most recently added files at the top and descending based on recency of upload.

Implementation Plan

The following functions need to be added...

@as1729 I'm testing in staging and I'm not sure this one is working properly - I've filtered the table for treasury files only, and I'm seeing two uploads for the same quarter/agency/EC code combo display
