Refactor messaging system to utilize LiteCqrs library

- Replaced instances of the previous messaging system with LiteCqrs across various application components, enhancing the CQRS implementation.
- Updated dependency injection to register LiteCqrs services and behaviors, streamlining command and query handling.
- Adjusted multiple command and query handlers to align with the new messaging framework, ensuring consistent functionality and improved maintainability.
- Added LiteCqrs package reference in the project file for better dependency management.
