Add new assets and implement minimap functionality

- Added new image assets for game over screens: `game_over_dead_bg.png`, `game_over_victory_bg.png`, and their respective Aseprite files.
- Introduced a new `Minimap` class to manage torch placement and rendering on the minimap.
- Implemented methods for adding and removing torches, updating the grid area, and drawing the minimap based on the current state of the game.
- Enhanced the minimap display with color coding for walls, empty spaces, and torches.
