Replaced hardcoded Debug paths in all .csproj files with $(Configuration) for AyCode and FruitBank DLL references, enabling correct DLL resolution for any build configuration. Switched appsettings.json connection string to use the FruitBank_PROD database. Added a null check for StockTaking in StockSignalREndpointServer.cs to prevent possible null reference exceptions. Noted some encoding issues in .csproj comments and copyright fields. No other functional changes.
Re-enable Product class and related enums in Nop.Core.Domain.Catalog, moving them from commented to active code. Add [ToonDescription] attributes to Product properties for enhanced documentation and serialization. Mark sensitive Customer fields with [ToonIgnore] to exclude them from Toon processing.
