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.

 ## DevExpress Components
 1. **DevExpress Blazor 25.1.3** — always use `DxGrid`, `DxFormLayout`, etc. Do NOT mix with generic Blazor component libraries.
 2. **Grid system** uses `AcSignalRDataSource` for real-time data — grids fetch data via SignalR, not REST.
