Speed up animations and reduce CPU turn delays

- Reduce move animation durations by 40% for snappier card movement
- Widen and slow down turn indicator shake for better visibility
- Cut CPU turn delays significantly:
  - Pre-turn pause: 0.6s → 0.25s
  - Initial look: 0.6-0.9s → 0.3-0.5s
  - Post-draw settle: 0.9s → 0.5s
  - Post-draw consider: 0.6-0.9s → 0.3-0.6s
  - Post-action pause: 0.6-0.9s → 0.3-0.5s
