feat: Add JSON-based action invocation to ActionPool

- Extend action_gen macro to generate JSON serialization logic
- Implement generic action processing using JSON text for type-agnostic calls
- Add callback mechanism with action name and arguments in ActionPool
- Update client and server registries to use new callback system
- Improve action system flexibility at the cost of serialization overhead
