enhance uno game animations and emotional feedback

- Add opponent emotion reactions (upset/happy) for specific game events like skips, draws, and wild card plays
- Differentiate animation durations and effects between local player and opponents
- Implement showcase animation for opponent's played cards with a grow/shrink effect
- Adjust card fly and stagger timings for opponent animations to improve visual clarity
