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.
- Introduce MgEditState enum and expose EditState on IMgGridBase
- Replace event-based syncing state with property-based state
- Redesign MgGridInfoPanel to support both view and edit modes with dynamic DevExpress editors and two-way binding
- Add visual distinction for edit/view modes in info panel
- Replace FruitBankToolbarTemplate with generic MgGridToolbarTemplate; toolbar adapts to grid edit/sync state
- Update all grid usages to use new toolbar
- Improve robustness, error handling, and maintainability throughout grid, info panel, and toolbar code
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.
