yaze/src/app/editor/dungeon/dungeon_editor.cc
scawful a71f1e02c9 Add Dungeon Room and Object Selection Features 
- Introduced new classes for DungeonRoomSelector and DungeonObjectSelector to enhance room and object management within the dungeon editor.
- Implemented UI components for selecting rooms and entrances, allowing users to easily navigate and manage dungeon layouts.
- Added functionality for rendering room graphics and object previews, improving the visual editing experience.
- Updated the DungeonEditor class to integrate the new selectors, streamlining the overall editing workflow.
- Enhanced error handling and validation in room and object management processes to ensure robust functionality.
