R5: CongressTrading als Strategie (Signal -> ExecutionService) + Positionen im Modul-Fenster

- CongressTradingStrategy: neuer Scrape-Trade -> TradeSignal (buy/sell-Mapping, sonst ignoriert)
  -> Core-IExecutionService; CongressScrapeWorker ruft sie je neuem Trade (try/catch-isoliert)
- Modul-Fenster: offene Positionen des Moduls via IPortfolioService.GetPositionsAsync("CT")
- Tests: CongressTradingStrategy (Mapping/Ausfuehrung, gemockter ExecutionService) -> 51/51 gruen
- Handel bleibt sicher aus (TradingEnabled=false + NullBrokerClient), bis Broker+Freigabe
- Build + smoke-ui + App-Start ok
