chore: update combat engine formatting and battle scene animations

- Normalize whitespace and alignment in `src/combat/CombatEngine.js` (variable assignments and filter calls).
- Extend projectile tween duration in `src/scenes/BattleScene.js` from 350ms to 2000ms for smoother visual effect.
- Adjust sprite pulse animation scale range from 0.8–1.5 to 0.5–1.0 for a more subtle effect.
- Update binary assets: new `smite2.mp3`, modified `fortify.mp3` and `smite-cast.mp3`, updated `attacks.png` and `attacks.psd`, removed duplicate `attacks (1).png`.
