Atlas: Phase A Integrations-Konzept + Cockpit + End-Screen

- Integrations-Konzept dokumentiert (App/docs/integration-konzept.md)
- Module-IDs vereinheitlicht: sim-XX -> semantische IDs (klima/heli/fluss/logistik/...)
- class_modules um current_level + quiz_enabled Spalten erweitert
- modules.php liefert dynamisch aus module_info, inkl. forcedLevel, quizEnabled,
  play_url, dueDate; neuer Filter ?module_id=X fuer einzeln
- schueler.html Cockpit: komplett API-first, teacher_started-Sektion als
  Auftrags-Block, neue IDs, Sprachregel 4a (Starten statt Spielen)
- teacher.html: Hardcoded ALL_MODS entfernt, laedt dynamisch
- Design-System: .ggs-endscreen-Komponente fuer einheitliche Modul-Abschluesse
- index.html Landing-Links gefixt: App/modul-X -> modul-X, V1-HTMLs auf
  Front-Controller-Routen (fluss, heli-game, stadt)
- 6 Inbox-Auftraege an Instanzen (Klima/Heli/Fluss/Logistik/Lehrplan/Glossar)
