Make people sign in to get the agreement

Currently we have a bunch of users who aren’t signed in asking us for
the agreement.

This is bad because:
- it’s slower (for them) than just being able to download it
- it creates work for us

We can’t just offer the agreement to anyone, but we can offer to it to
anyone who’s signed in because we now let people self-select which
version to download when we can’t tell which one to give them.
