Enhance tile rendering and update logic in OverworldEditor and Canvas

Browse Source 
- Added checks to ensure tile16 blockset is loaded and active before drawing in OverworldEditor.
- Improved tile rendering logic in Canvas to pre-render tiles and ensure they are active before drawing, preventing timing issues.
- Cleared cached tile bitmaps to force re-rendering when the tile16 blockset is updated, enhancing visual consistency.
