While doing this, I have also fixed a bug in the current implementation
of ThrowAll (formerly named `throwAll'`).

It integrates servant-routes which allows to list and export the
server backend routes.

This commit moves `GargConfig` and the other config-related
data structures back into gargantext, so that they can be edited
and expanded without needing to worry about the prelude project.

This is a first stepping stone in avoiding bugs by having `UserId` and
`ContextId` being proper types, and not synonyms.

We also refactor things to have `AuthenticatedUser` carry the `UserId`.

Basically, Gargantext.Prelude exports all of Protolude now.

Based on the suggestions in
https://kodimensional.dev/space-leak

Now the job doesn't return 'succeeded' fields when it actually fails.
