RF-Slice 1: ResolutionFarming-Modul-Skelett + geldkritische pure Logik + Tests

Neues Strategiemodul PolyTrader.Modules.ResolutionFarming (IPolyTraderModule,
Name=ResolutionFarming, DbPrefix=rf_), in Solution/App/Tests + beide Modul-Listen
in Program.cs eingebunden. Skelett laedt (RegisterServices/UI noch no-op).

Geldkritische Entscheidungslogik pur und vollstaendig unit-getestet:
- FarmingRiskEngine: Netto-Edge nach Fees (NetEdge/NetEdgePct/HasEdge), Positionsgroesse
  unter Markt-/Cluster-/Gesamt-Exposure-Limits (AllowedPositionUsd), Kill-Switch, Tages-Drossel.
- FarmingScanner: Preisband, Kategorie-Whitelist, Blacklist, Cluster-Key (korrelierte
  Favoriten teilen einen Cluster), Kandidaten-Score.
- FarmingFillModel: Shares fuer Budget (2-Dezimal-Floor), Resolve-PnL (Auszahlung - Kosten -
  Entry-Fee, Maker/Taker), Einstiegskosten inkl. Fee. Nutzt Core.FeeModel.
- RfSettings (rf_settings) mit konservativen Defaults + PropertyGrid-Attributen.

39 neue Tests. Build 0 Fehler, 283 Tests gruen, --smoke-ui ok.
Persistenz (DbContext/Migration/Repos), Scanner-/Monitor-Jobs, Execution und UI folgen.
