Refactor SignalR client DI and config, add test factory
Refactored FruitBankSignalRClient construction to use DI and centralized configuration from appsettings.json across all platforms. Introduced TestSignalRClientFactory for consistent test setup. Added FruitBankHubConnectionExtensions for reusable SignalR connection and logging configuration. Updated Program.cs and MauiProgram.cs to register logger factories, log writers, and IHubConnectionBuilder via DI. Embedded appsettings.json in MAUI and updated .csproj references for build flexibility. No business logic changes; all updates are infrastructure and test setup.
- Refined type metadata serialization: collections and dictionaries are now detected and described more accurately, avoiding generic type names (e.g., List`1) and redundant "object" element types.
- Added circular reference protection to type name generation to prevent stack overflows and duplicate type names.
- Updated AcToonSerializerOptions.Compact to use indentation for better readability.
- Introduced ToonTests with unit tests to ensure type metadata correctness, uniqueness, and clarity.
- Added AyCode.Core project to the solution and adjusted namespaces/usings for consistency.
- Introduce AcExpressionHelper and related classes for serializing/deserializing LINQ Expression trees and IQueryable queries to/from JSON, enabling remote transport and execution.
- Add MgGridSignalRDataSource<TDataItem, TId> for instant local filtering and background refresh in DevExpress grids using SignalR.
- Update bunit NuGet package to v2.4.2 in test projects.
- Minor: update FruitBank base URL comment, add new test in OrderClientTests.
- Replaced DxWindow with custom Bootstrap 5 fullscreen overlay for grid components, improving fullscreen UX and styling.
- Added new CSS for fullscreen overlay, header, and body; retained legacy DxWindow styles for compatibility.
- Introduced SignalRSerializerDiagnosticLog flag to control binary serializer diagnostics at runtime.
- Enabled diagnostics in DevAdminSignalRHub, FruitBankSignalRClient, and Program.cs based on the new flag.
- Updated OrderClientTests to use GetStockTakings(false).
- Added StockTakingSerializerTests for binary serialization/deserialization validation and debugging.
Refactored `OnDataSourceLoaded` to be asynchronous for better state handling. Downgraded `Newtonsoft.Json` to version `13.0.3` across multiple projects for compatibility. Enhanced `MeasuringItemPalletBase` with `SetParentPropToNull` and `SetForeignKey` methods. Refactored `OrderItemPallet`, `ShippingItemPallet`, and `StockTakingItemPallet` to simplify table attributes and improve parent-child relationship handling.
Added `IsReadyForClose` to `StockTaking` for better closure validation. Updated SignalR tag constants to reflect new functionality. Improved Razor components (`PalletItemComponent`, `StockTakingTemplate`, `MeasuringIn`, `MeasuringOut`) to streamline logic and maintain proper references.
Introduced `JsonExtensionTests` for comprehensive validation of JSON serialization/deserialization, including deep hierarchies, circular references, and hybrid references. Added `test_debug.ps1` for streamlined test debugging. Performed general code cleanup and improved test coverage.
