Phase 5-UI: Launcher auf Toolstrip-Modell + SettingsView (Designer-first)

- LauncherForm: lstView-Ansatz entfernt (lstViews/colName/pnlBottom/btnOpen raus).
  Fenster werden ueber toolstrip_windows-Buttons geoeffnet/fokussiert:
  btn_settings -> Settings, btn_terminal -> Terminal (Bindung per stabiler View-ID).
- statusStrip_info: Live-Status (Trading, Modul-Anzahl, API WSS/Polling) via 1s-Timer.
- toolstrip_quickbar bleibt fuer Schnellaktionen (Trading an/aus) reserviert.
- Neue SettingsView (UserControl + Designer): ServerSettings-PropertyGrid +
  Speichern/Neu laden; Verhalten wie bisheriger Settings-Tab. In Program.cs registriert.
- Build 0 Fehler.
