refactor(editor): remove EditorCardManager references from various editors

- Eliminated the inclusion of EditorCardManager from multiple editor header files, streamlining dependencies and reducing coupling.
- Updated comments in PaletteEditor to reflect the transition to EditorCardRegistry for card management.

Benefits:
- Enhances modularity by decoupling editor components from the centralized card manager.
- Improves maintainability and clarity in the codebase by aligning with the new card management approach.
