Worklog for task "Organize integration of the new frontend with the existing MODX backend"

Since even in the medium term all the business logic will still revolve around MODX itself, but the entire frontend must work seamlessly on new technologies, we are implementing a gradual synchronization of user accounts into the database of the new engine. That is, when a request from the current user arrives with their MODX session cookie, we simply check their session on our new backend, retrieve the MODX user, and create a linked user on our side. At the same time, we don't even need to store the password or check access rights, since verification still goes through MODX anyway, and all access policies continue to work at the MODX level, as everything was originally built on the API here, so we will simply proxy the requests. And on the frontend, we only need to know whether the user is authorized or not.
