Frontend setup

[decima]

There is a route existing for setting up the project :
create the first user etc etc

POST {{hostname}}/setup
Content-Type: application/json

{
  "username": "decima",
  "password": "password"
}

this route should also setup a jwt key in a config file but one issue at a time!

There is no front on this route, but we should have, so let's add some and ensure the user cannot use the app without calling an initial setup.
