Summary

Make login/register UI pages

Detailed description

There is a need to create a user interface people can use to create accounts, and later log into the app.

This also means a system for storing current user JWT has to be developed.

(Optional) Technical description

When sending the correct credentials to the login endpoint, the server will answer with a JWT which can later be used as a bearer token for authorized requests.

The UI needs to store such token.
