feat: Enhance Dungeon Rendering with Size Adjustments and Testing Initialization

Browse Source 
- Added InitializeForTesting method in Rom class to facilitate testing setup.
- Updated DungeonCanvasViewer to adjust object and sprite sizes from 16x16 to 8x8, improving rendering accuracy.
- Modified rendering logic for various dungeon objects (chests, doors, walls, pots) to reflect new size calculations.
- Adjusted object position calculations in ObjectRenderer to align with the new size metrics, ensuring consistent rendering across the application.
- Updated integration tests to verify the new initialization method for ROM objects.
