It's better to enumerate fields than not - easier to search later.

Also, a performance improvement for queryNgramsOccurrences (no VALUES).

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

This allows us to have only one single (static) map which will be
treated by GHC as a CAF.

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.

- DBCmd instead of Cmd
- remove FlowCmdM in favor of HasNodeStory

This doesn't block the whole view for the (long) period of refreshing
it.
