Configure initial app hosting

[mackcooper1408]

you'll need some environment variables, so it's probably best to wait until #27 is done before starting this

Context

We should move to get a working "live" version of the app up and running so that we can quickly pass around to non-eng people what we have done and what's still in progress.

Definition of Done

1. App hosting configuration is setup and a working "live" demo site is available for access

Engineering Details

1. Since we're using NEXT, this is likely easiest done via Vercel (with serverless python functions for the backend), but there are certainly plenty of options for making this happen... The priority is easy to manage and free / cheap

@leela-solomon @agennadi @AdamFinkle This should be a priority for the team. Vercel and fly.io don't support multi-container deployments, so our options are both limited and potentially more expensive if we want to go that route. As it was said above, I believe we should prioritize ease of use and free, so I'd consider simplifying for the sake of deploying quickly.
