Phase 5-UI (Proof-of-Pattern): Launcher-Shell + erste extrahierte View (Terminal)

- Ui/LauncherForm: schlanke Startleiste, rendert Buttons dynamisch aus den registrierten Views (gruppiert) + Legacy-Button fuer das alte Tab-frm_main. - Ui/ViewHostForm: generisches Host-Fenster fuer eine View (Control docked fill). - Ui/ShellUiHost : IModuleUiHost: sammelt Views, oeffnet Einzelinstanz-Fenster. - Ui/Views/TerminalView: erste designbare View (UserControl + Designer.cs); Terminal-Logik aus frm_main extrahiert; DI via Initialize(TerminalLogger) -> parameterloser Ctor bleibt fuer den VS-Designer nutzbar. - Program.cs: startet jetzt LauncherForm (statt frm_main), registriert die Terminal-View; App bleibt via Legacy-Button voll bedienbar. - Build 0 Fehler.
