Scale 2048 to fill screen

Browse Source 
2048.lua:
- Removed hardcoded TILE_SIZE and TILE_SPACING constants
- Added get_tile_size() function that calculates tile dimensions based on screen width
- Added get_grid_start_x/y() to center grid
- Updated draw() to use dynamic sizing for all tiles
- 4x4 grid now scales proportionally on any screen size
