Modul-Views: parameterloser Ctor + Initialize() (Designer-öffenbar)

Browse Source 
Der VS-WinForms-Designer braucht einen parameterlosen Konstruktor, um eine Form
zu instanziieren. Die drei Views hatten nur einen DI-Ctor -> Designer hätte sie
nicht öffnen können. Umgestellt auf das Core-View-Muster (DashboardView):
- Parameterloser Ctor: InitializeComponent() + Event-Wiring.
- Initialize(deps): Abhängigkeiten setzen + Daten laden.
- Felder nullable + Null-Guards in den Handlern.
- CopyTradingModule.RegisterUi: new View() + view.Initialize(...) statt DI-Ctor.

Verifiziert: Build grün, --smoke-ui grün (3 Accounts / 32 Trader, alle Views OK).
