refactor(mocks): unify Mock.Of<T>() and Mock.OfPartial<T>() into sing…

…le API

The source generator already knows whether T is an interface or a class,
so users shouldn't need to choose between Of and OfPartial. This follows
the convention of other mocking frameworks (Moq, NSubstitute) where a
single factory method handles both cases.

- Merge _factories and _partialFactories into a single unified registry
- Remove Mock.OfPartial<T>() and MockRepository.OfPartial<T>()
- Add Mock.Of<T>(params object[] constructorArgs) overloads for classes
- Derive IsPartialMock from TypeKind.Class in source generator
- Fix [GenerateMock(typeof(ConcreteClass))] to generate partial mock code
- Update analyzers, tests, snapshots, and documentation
