Add Komodo enemy class and enhance enemy spawning logic

- Introduce Komodo class with high health and attack mechanics.
- Modify Enemy class to accept type parameter during initialization.
- Update EnemyAI to set speed based on enemy type.
- Implement random spawning of enemies in boss rooms.
- Adjust health bar calculations to use max health.
