fixed proxy + converted to npm

[Kirbyasdf]

Updated to work with npm (now superior to yarn) and fixed the proxy issue when running locally....see below for working site....please note that when setting up your netlify site you must change the build command from yarn build -> npm run build in settings.

if you want to still use yarn, simply change the netlify.toml file and copy the yarn.lock file from create-react-app-lamba master history or you can just take the setupProxy.js file and place it in the current repo.
