feat: Introduce DungeonEditorV2 with component delegation for improved architecture

- Added DungeonEditorV2 to streamline dungeon editing by delegating tasks to specialized components.
- Implemented comprehensive integration tests to validate functionality and ensure proper ROM handling.
- Achieved 100% pass rate for all integration tests, enhancing reliability and performance of the editor.
- Updated test suite to include tests for the new editor, ensuring robust coverage and error handling.
