refactor: Introduced a SessionCardRegistry and WindowDelegate for better session management in the editor.

Benefits:
- Streamlines the build process by allowing for multiple Protobuf targets, enhancing compatibility and maintainability.
- Improves session management capabilities within the editor, leading to a more organized and efficient user experience.
- Enhance Protobuf target handling in CMake configuration
- Updated CMake files to support multiple Protobuf targets, improving flexibility in linking.
- Adjusted target link libraries across various components (yaze, yaze_core_lib, yaze_editor, etc.) to utilize the new
