Motivation and Context
The Dapr Runtime uses string-based class names to load step classes dynamically. This PR adds validation to ensure that only valid KernelProcessStep subclasses can be loaded and instantiated, improving type safety and providing better error messages when misconfigured.
The new allowed_module_prefixes parameter gives users control over which modules are permitted for step class loading, which can be useful in environments where stricter control is desired.
