feat: enhance steam train coal shoveling visual feedback

Added dramatic visual effects to make coal shoveling more obvious:
- Enhanced shoveling animation with bigger movements and brightness
- Flying coal particles from worker to locomotive
- Steam puffs rising from train chimney on correct answers
- Glowing momentum bar with flash effect
- Context-specific feedback: "Coal shoveled! +X% momentum!"

Creates clear cause-and-effect visual connection between correct answers
and train speed increases for better player understanding.
