refactor(editor): integrate EditorCardRegistry for improved card management

- Updated EditorManager and various editor components to utilize EditorCardRegistry for card registration and visibility management, enhancing dependency injection and modularity.
- Refactored card registration logic across multiple editors, ensuring a consistent approach to managing editor cards.
- Improved UI coordination by delegating visibility checks and card management to the new registry, streamlining the user experience.

Benefits:
- Simplifies card management, leading to a more organized and efficient user experience.
- Enhances maintainability by clearly defining roles for card handling and editor operations, aligning with the overall architecture improvements.
