Telescopetest-io: Add content filtering for uploads

## What is the problem your feature solves, or the need it fulfills?

Currently, anyone can upload anything to production telescopetest.io and it will just be there for anyone to look at. We want some way of moderating the content that can be displayed on telescopetest.io.

## Describe the solution you'd like

We need some way of content rating and then filtering of results listed on the /results page. We can do this with AI, and have some kind of flag for whether content is harmful/inappropriate. If content is flagged, it should not be listed under results.

If someone wants to see flagged content, they will need to do so by spinning up a local instance of telescopetest-io and viewing results there. Local development with telescopetest-io should have the ability to turn off/remove this content filtering.
