Optional authentication on pages

[NathanPB]

Currently, we are not using all the potential of NextJS because on the server side render, the authentication is not set, and all the pages requires authentication (if not authenticated you will be redirected to the login screen at any point).

This makes SSR and SG completely unusable because the server is actually rendering just the login screen.

Along with #6 which introduces the concept of making data public, we will be able to make routes that does not require authentication. Instead, renders the "public version" of the page when not authenticated and do not perform weirdo redirects.

However, pages like /me will need authentication anyway...
