Refactored Mango.Sandbox.EndPoints to enable minimal, dependency-light SignalR endpoint testing. Introduced DevAdminSignalRHubSandbox and TestSignalREndpoint for protocol/contract tests without full NopCommerce/FruitBank infra. Added SignalRClientSandbox and comprehensive MSTest coverage for all parameter types. Simplified Program.cs startup, updated project references, and added minimal logger. Original SignalREndpointTests replaced with focused, low-level and high-level tests. CORS and DTOs updated for compatibility.
Enhanced stock-taking functionality by introducing the `CloseStockTaking` method in `StockTakingDbContext` to manage session closures with validation. Added the `IsReadyForClose` method to `IMgStockTaking` and its implementation in `MgStockTaking`. Integrated `FruitBankDbContext` for stock updates.
Improved logging in `StockSignalREndpointServer` and added a new SignalR endpoint for closing stock-taking sessions. Updated `AddStockTaking` to initialize properties for new entries.
Simplified loading logic in `OrderItemDtoDbTable` by commenting out unnecessary `.ThenLoad` chains. Enhanced validation in `RefreshStockTakingItemMeasuredValuesFromPallets` and adjusted return statements in `AddOrUpdateMeasuredStockTakingItemPallet` and `UpdateStockTakingItemPallet` to fetch updated entities.
These changes improve maintainability, robustness, and functionality across the codebase.
