refactor: Admin-Layout komplett entfernt — SDK als einziges Layout

Kaputtes (admin) Layout geloescht (Role-Selection, 404-Sidebar, localhost-Dashboard).
SDK-Flow nach /sdk/sdk-flow verschoben. Route-Gruppe (sdk) aufgeloest.
Root-Seite redirected auf /sdk. ~25 ungenutzte Dateien/Verzeichnisse entfernt.
