Move boss to new scripts

Implementation description

Implements cactus boss scripts into scenes/demos/Test New Boss

Adds:

• Boss health bar
• Boss contact and ranged attacks
  Fixes:
• Enemy health bar (also adds a outline if wanted) - will need to replace with the new prefab to use

Steps to test

1. Open the Test New Boss scene and play around with boss
2. Does it feel like reasonable attacks? Anything else to add/change
3. Verify boss health bar looks good at top of screen, enemy health bar follows boss

What should reviewers focus on?

What kind of health bar is better, outline or no outline?

Any other attacks to add/change/balance?

Pretty nice! Code is easy to follow and the vacuum attack is a cool mechanic.

The boss health bar works, though maybe later we could locate it at the bottom since it may be confused with the player's health bar. The outlined health bar looks better in my opinion.

The boss was quite difficult to defeat using melee attacks (I used ranged attacks from a distance instead). That might be due to boss melee animations not being implemented yet so we couldn't predict/see its moves, but not a big problem since we could build the boss fight arena so that the player can hide and strategically shoot the boss with ranged attacks.

If you would like to make further changes, please do so! Maybe you could nerf the boss a bit (melee attack damage is high, player could barely approach it especially with the vacuum attacks), but otherwise the boss is very well done. Feel free to merge to main anytime
