feat: Enhance graphics loading and editor synchronization

- Implemented default palette application during graphics data loading to ensure immediate visibility of graphics sheets.
- Refactored GraphicsEditor to queue texture creation without palette management, improving performance and clarity.
- Introduced NotifySheetModified method in Arena to handle texture updates across all editors, ensuring consistency in graphics rendering.
- Enhanced logging for better tracking of graphics sheet modifications and texture operations.
