UI Slice 3: CopyTrading - Zeilenfaerbung, Filter, Offene-Trades-Tab, Master-Grid-Fix

- Geschlossene Trades: Zeilenfaerbung nach PnL-% (TradeRowColoring, pur+getestet: <0 rot,
  0-10% hellgruen, >10% gruen) via DataBindingComplete. Filter-Panel (Designer): Markt (Text),
  Master-Trader (Combo, dynamisch), Ergebnis (Alle/Gewinner/Verlierer), Von/Bis (optionale
  DateTimePicker mit Checkbox), Zuruecksetzen. Summary zeigt gefiltert/gesamt.
- Neuer Tab 'Offene Trades' (OpenTradesView, designerfaehig): alle offenen Positionen aus dem
  Laufzeit-State mit Entry/Aktuell/Wert/Buchgewinn/-% und Status (offen/Exit laeuft), Zeilenfaerbung
  nach Buchgewinn-%, Summenzeile. In CopyTradingMainForm zwischen Master-Trader und Geschlossene eingehaengt.
- Master-Trader-Grid: AutoSizeColumnsMode=Fill + FillWeights -> Spaltenbreiten teilen sich immer die
  Breite (Fix der 'verbuggten' Breiten); RowHeader war bereits aus.

Tests: +8 (TradeRowColoring-Schwellen). Build 0 Fehler, 396 Tests gruen, --smoke-ui gruen.
