Login handled in-browser #75
Description
The login page has a JavaScript function that handles login, which means the web browser needs to be able to contact the backend.
This is not ideal, because it forces the backend to be exposed externally, rather than just safely hidden away in a docker network with the other containers.
Ideally, only the frontend should be exposed externally (and ideally proxied behind something like Traefik that can add a layer of isolation).
