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.
Introduces a new SANDBOX environment with a dedicated web app (`Mango.Sandbox.EndPoints`) for testing SignalR endpoints in isolation from the main application. Adds null plugin manager implementations to avoid plugin dependencies. Includes automated MSTest tests (`Mango.Sandbox.EndPoints.Tests`), a manual SignalR test client, and a PowerShell script for building and running the sandbox. Provides configuration files and health endpoints for robust, independent development and testing of FruitBank SignalR logic.
