CLO-35 Write tests/Add Github actions integration

### Context Testing needs to be done on all endpoints. ### Description Besides using vitest with cloudflare workers, the [cloudflare worker deployment action](https://github.com/marketplace/actions/deploy-to-cloudflare-workers-with-wrangler) can be used to automatically push to production. ### Acceptance Criteria * The tests all pass * The Github actions run tests * The Github action deploys to production *after* the tests pass, not on git push.
