Fix wrong path used by backend (#14352)

After moving a section on the frontend, this broke the path that was
sent by email on the backend.
This kind of error comes back every ~2-3 month under different forms so
we need a more robust solution: I moved routes to the shared folder,
that way we will share one common source of truth between the frontend
and the backend.

Fixes #14343
