fix: correct collision message and improve asset loading

- Fix typo in collision message from "Ihr seit koolidiert!" to "Es gab eine Kollision!"
- Reorder TODO comment in endGame method
- Rename "Früchte" folder to "Fruits" for consistency
- Add TileLoader class to preload and cache game assets
- Refactor Overlay class to use TileLoader for improved image handling
