chore(refactor): remove shared folder dependencies to the server

Many files from the `shared` folder were importing files from the `server` folder.
When attempting to use Typescript project references to describe dependencies,
it highlighted a circular dependency beetween `shared` <-> `server`.

The Typescript project forbid such usages.
Using project references greatly improve performance by rebuilding only
the updated project and not all source files.
