Get rid of SSR

[ghost]

right now, if you visit apply.hackbeanpot.com on a cold cache, it takes kinda long to load the page, like between 2-5 seconds. this is not ideal.

basically, it's because we're trying to SSR the index page, to either redirect to login or show dashboard. HOWEVER this is slow because we need to hit mongo in order to know which page to load.

instead, we should remove SSR and just make the login page /, and move the dashboard page to /dashboard

also get rid of the serverSideProps or whatever the SSR function is in the CURRENT index page (soon to be dashboard page)
