Enhanced snail entity with new features

Added a sprite to the Snail class and implemented animations for the snail's movements. The snail now has a body and shell texture, along with an eating shadow. Also, added logic to flip the sprite based on movement direction in the 'snail_eating' state. Furthermore, made CollisionShape2D invisible for better aesthetics.
