Prevent serverless function timeout

[frontendphil]

We're calling out to a bunch of different services. When these services error, we can wrap code in try...catch and handle service outages. However, when these services take a very long time to respond, we might exceed the timeout for serverless functions, and our users are left with a very unpleasant Vercel error page.

We could prevent this by racing requests to other services with a promise that resolves before the serverless timeout is reached and then treat these timeouts as "regular" application errors.
