Phase 3a: Core-Domänenmodelle in den Core verschoben

- AccountState, Position, MarketData nach src/PolyTrader.Core/Models/
  (Namespace PolyTraderSharp.Models beibehalten → keine Consumer-Änderung).
- AccountState: ungenutzte usings (MongoDB.Driver, PolyTraderSharp.Extensions)
  entfernt (Core darf App-Shim nicht referenzieren).
- MongoDB.Driver 2.24.0 als Core-Paket (für BsonId-Attribute).
- Build 0 Fehler.
