Convert from SSG to SSR

[binoy14]

What?

We will use Fastly in front of Vercel as a CDN/caching layer (see #10). Therefore, we will convert from Static Site Generation (SSG) to Server Side Render (SSR) with caching. Eventually, we'll use cache invalidation when data changes – but for this ticket, we should focus on converting from SSG to SSR.

How?

In the NextJS page files, instead of using getStaticProps, we should use getServerSideProps so that our page data is fetched each time the page is fetched from Vercel.
