This commit maps the "Publish" action inside CodiMD/HedgeDoc to the
share URL feature.

This commit improves a bit the ShareURL internal API by wrapping the
returned URL into a proper `ShareURL` type (that internally uses a typed
representation for the URL).

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

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.

Using goldenVsStringDiff creates problems with CI trying to locale
`gargantext-cli -- golden-file-diff`.

This beefy commit removes the old (unnamed) Servant API.

This big commit ties the knot with the named _routes_ by providing
concrete server (i.e. handlers) implementations.

This big commit adds a separate module hierarchy for Servant named
routes (see https://www.tweag.io/blog/2022-02-24-named-routes/ ) which
will make working with servant endpoints more pleasant (especially when
it comes to emitted errors).

This still doesn't do anything to wire the routes to the concrete
handlers.

After Fabien's changes, this needed amendment.

This commit moves away from generic-derive JSON istances for `NodeType`,
as we know that the frontend will be relying on this in the GraphQL API,
and we don't want them to silently break the frontend during
refactoring.

It forces programmers to think about errors we are logging and reporting
to the frontend, because they need to contain no sensitive data.

Apparently `dot` has a long lasting bug (recently fixed) which is the
root of the non-determinism:

This was (User, Either CorpusName, [CorpusId]) before, but the case of
UserMaster doesn't make sense with these parameters, so I rewrote the
function to accept only correct datatypes as inputs.

This contains only data, removes some Database dependency in imports.

This reverts commit f4284b4e.

This paves the way to a more effective search in corpus by modifying the
internal "leaves" type of the `Query` type from a `Term` to a new type
called `QueryTerm`, which can either be an extact match or a partial
match, which can be rendered into a proper Postgres TS query via the
":*" syntax.
