Add celebration animations when voting on mood

- Create 10 full-view celebration animations (vortex, explosion, flip, shatter, pulse wave, fireworks, confetti, morph, tunnel, gravity)
- Play random animation when user votes in-app
- Add Animation Lab debug view to preview and test animations
- Animations complete before saving mood to prevent view flash
