Phase 5-UI: Copytrading-Modul-Views (Master-Trader, Closed Trades, Account-Settings)

- MasterTradersView: Liste + PropertyGrid-Editor + Account-Zuweisung
  (CheckedListBox -> AssignedAccountIds), Neu/Speichern/Loeschen; persistiert
  via ITrackedTraderRepository + synct CopyTradingState.Traders.
- ClosedTradesView: read-only Grid der geschlossenen Copytrades mit
  aufgeloesten Account-/Trader-Namen + Kurzauswertung (ICopyTradeLogRepository).
- AccountSettingsView: Account-Auswahl + PropertyGrid fuer
  CopyTradingAccountSettings, Speichern via Repo + State-Sync.
- IPolyTraderModule.RegisterUi erhaelt jetzt IServiceProvider (Module loesen
  ihre View-Abhaengigkeiten auf); Program uebergibt viewServices.
- CopyTradingModule.RegisterUi registriert die 3 Views (Group "CopyTrading").
- LauncherForm haengt Modul-Views dynamisch als Buttons an toolstrip_windows
  (Core kennt keine Modulnamen; Bindung nur ueber View-IDs).
