Add feature flag for fake marking results as sensitive

Fixes #854 by @zackkrida

Description

This PR adds a feature flag fake_sensitive to mark roughly half the results as mature. It uses a random (but deterministic) approach which allows results to be marked mature consistently and across Pinia stores and browsing sessions.

This PR makes no UI changes. It is limited in scope to just adding the feature flag and setting up its behaviour. UI changes are already necessitated by #791 so this PR does not put in effort that's destined to be repeated.

Testing Instructions

0. Check out the PR and run the dev server.
1. Enable the flag 'fake_sensitive' from /preferences.
2. Search for somethine.
   • You will see the console logs printing Fake mature <uuid4> for ~50% of results.
   • This list should remain the same no matter how many times you refresh the page.
3. Pick any ID out of this list and see the single result page for that ID.
   • You should get the Fake mature <uuid4> log again because it also works on the single media store.

This approach works perfectly. Awesome. Do you think it's worth creating a little utility function for the mature detection so the logic doesn't need to be updated in two places? Something like:

const fakeMature = (item) => {
  if (prng(hash(item.id))() < 0.5) return
  item.mature = true
  log("Fake mature", item.id)
}

I don't think it's necessary but something to consider.

I also tried this with some blurring, which was a fun way to test:

Good point, I'll extract it to a separate utility 👍. Update: done in b57157d.

Wow, I didn't know we didn't have this in the type! Great catch! Is it always available, or should we mark it as optional?

[dhruvkb]

It's always available.

Really nice! I have a question about mature type inline, but don't want to block the PR.
