- Add endpoints and tests for binary serialization of TestCustomerDto lists to reproduce and diagnose MessagePack interned string index errors
- Update appsettings.json to use FruitBank_PROD database
- Set AcBinarySerializerOptions in DevAdminSignalRHubSandbox
- Extend TestSignalRTags and ITestSignalREndpointServer for new endpoints
- Add TestCustomerDto class for serialization tests
- Remove obsolete low-level SignalR/HTTP endpoint test files
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.
