Fix magazine and bullet usage limits

- Fixed bug where players could use magazines beyond their level's maximum limit
- Added validation to prevent using bullets when magazine is already full
- Magazine items now respect level-based limits (e.g., 3 magazines at level 1)
- Items are not consumed from inventory if they can't be used due to limits
- Added proper error messages for when limits are reached
- Updated ShopManager to work with LevelManager for limit validation
