Attachments filters and sorting don't work [4]

Nobody has claimed this yet.

Describe the Bug:

Probability (how likely the bug is to happen, scored from 1-5): 2
(For example, probability of 5 is something like "it happens to all users every time they log in."
Probability of 1 "only happens to certain users when a really specific and unlikely path is followed.")

Effect (how bad the bug is when it does happen, scored from 1-5): 2
(For example, effect of 5 is "the entire app crashes and makes it unusable for all users" or "the bug causes the wrong data to be saved, with critical information (e.g. payment) being affected."
Effect of 1 is "It makes some styling look a little bit weird.")

Steps to reproduce the behaviour:
- in dev
- add an attachment to a project
- try to filter by any of the filtering options
- non-matching items aren't removed from view
- try to sort
- nothing rearranges

- Additional context

No files, tests, or entry points are named. Start by locating the project attachment view and reproduce the filtering and sorting steps there; done means filters remove non-matching attachments and sorting changes their displayed order.
