R7: Dashboard-View + DashboardService (Abschluss Feinschliff)

- Core/Trading/DashboardService: aggregiert Positionen/Exposure/Trades via EF (DashboardSnapshot)
- UI/Views/DashboardView: Trading-Modus, aggregierte Kennzahlen, geladene Module (+ Aktivierungs-Status)
- core.dashboard-View registriert (Order 5) mit dashboard-Icon
- Tests: DashboardService (leer + Aggregation, InMemory) -> 58/58 gruen; smoke-ui deckt alle 5 Views ab

Kurskorrektur R1-R7 abgeschlossen: IBKRTrader folgt dem PolytraderSharp-Konzept.
