Phase 7: Mapping-Randfälle + Parser-/Repo-Randfälle (78 Tests)

- DbContextModelTests: feinkörnige Modell-Invarianten - Dezimal-Präzision (18,6) auf Geldfeldern (Core + Settings), MaxLength auf Strings, manuell gesetzte Keys (ValueGeneratedNever), AssignedAccountIds hat Value-Converter + text-Spalte, MarketData JSON-Spalten = text, Indizes (TradeRecord.ClosedAt, MasterTraderHistory TraderId/ClosedAt). (GetColumnType() wirft unter InMemory -> Spaltentyp via Relational:ColumnType- Annotation ausgelesen.) - MongoExportParserTests erweitert: numerische statt String-Dezimale, unbekannte Felder ignoriert, mehrere Dokumente in Reihenfolge, AssignedAccountIds als String-Zahlen, IsActive-Default. - RepositoryEdgeCaseTests: GetAll leer != null, Update-Alias, Factory-Isolation, History-Exists/GetByTraderSince inklusive an den Grenzen. Alle 78 gruen. (Copytrading-Service-Logik bewusst noch nicht getestet - wird parallel ueberarbeitet.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
