create connections to the Firebase for backend and frontend portions of the app

[RonaldCrb]

currently the firebase code is only invoked in the frontend. we need to also invoke it from the backend portion so that we can authenticate as the editor@pleb.stream user

acceptance criteria:

• create firebase connection logic for the backend
• ensure editor@pleb.stream password is NOT prefixed with NEXT_PUBLIC_ and that is only accesible for the backend portion
