Phase 2: Launcher-UI + eigenstaendige Modul-Fenster

- Form1 -> LauncherForm (Dateien via git mv, Designer/resx angepasst)
- Modul-Tab: Karten aus ModuleRegistry mit "Fenster oeffnen"-Button je Modul
- UI/WindowManager: Fenster-Tracking (Key->Form), Re-Open fokussiert, CloseAll
- UI/ModuleFormBase: Basisklasse fuer eigenstaendige Modul-Fenster
- CongressTradingForm: DB-Kennzahlen + manueller Scrape-Trigger (Phase-4-Ausbau folgt)
- WindowManager in DI; Launcher schliesst Modul-Fenster beim Beenden
- Tests: WindowManager (6) -> 21/21 gruen; Launcher-Start verifiziert
