Phase 5.2: TradingState-Split (Core-State vs. CopyTradingState)

- Core TradingState (in Core): globale Schalter, Accounts, MarketCache, GlobalPnl.
- Neuer CopyTradingState (im Modul): Traders, MasterTraderPositions,
  TraderAnalyticsCache, TotalCopyTrades/GetNextTradeId, PendingOrderTimestamps,
  SixSharesMinimum.
- 10 Konsumenten umgestellt (Program, frm_main, CopyTradingEngine,
  TraderMonitor, Alchemy, WSS, Snapshot, StartupHydration, beide Analytics-Jobs):
  Modul-Felder von _state.* auf _copyState.* umgeleitet, CopyTradingState via DI.
- Rein mechanische Feld-Umleitung, keine Logikänderung. Build 0 Fehler.
