fix unit tests (#167)

* Fix DeepCopier mock issue in unit tests

- Register DeepCopier service instance in TestKitSilo to prevent TestServiceProvider from auto-creating Mock
- Resolves System.NotSupportedException: Type to mock (DeepCopier) must be an interface error
- Tests now run properly, reduced from 20 failures to 10 failures out of 230 total tests
- Only modified test code, no business logic changes

* Fix Logger NullReferenceException in unit tests - Register NullLoggerFactory to prevent Mock Logger issues - Achieves 100% test pass rate - Resolves all mocking issues in test framework

* feat:update test yaml
