Replace Reward = Time animation with clean pulse scale to eliminate edge artifacts

Animation Change:
- Reward = Time: Removed rotation and translation movements that caused edge artifacts
- New animation: Simple pulse scale (1.08 max) with no movement outside bounds
- Added 0.5s delay between color1 and color2 for rhythmic effect
- 3s duration for smooth, gentle pulsing like a heartbeat

Benefits:
- No more edge artifacts or visible boundaries
- Clean, professional pulsing effect
- Maintains the 'time passing' concept through rhythmic pulsing
- Perfectly contained within circular bounds
- Smooth and elegant animation

The pulse animation provides a subtle, sophisticated effect that represents time passing without any visual artifacts.
