🎬 Fine-tune all transition timing with centralized configuration

Implement Milestone 13 requirement: Timing fine-tuning for all transitions.

Changes:
- Create centralized timing configuration (src/config/timing.ts) with:
  - SPRING_CONFIGS: Unified spring presets (SMOOTH, SNAPPY, BOUNCY, etc.)
  - STAGGER_DELAYS: Consistent stagger timing for cards, lists, activities
  - TIMING: Scene-specific delay constants (intro, CTA, outro)
  - GLOW_CONFIG: Glow effect parameters (intensity, frequency, scale)
  - Helper functions: secondsToFrames(), getStaggeredDelay()

- Fine-tune all 8 portal scenes:
  - Reduced perspective rotations (30° → 25° / 20° → 18°) for smoother entrances
  - Increased initial scales (0.8 → 0.85-0.92) for subtler animations
  - Reduced Y translations (30-40px → 18-25px) for less jarring motion
  - Standardized glow frequencies using centralized config
  - Consistent spring configurations across all scenes

- Add comprehensive tests (src/config/timing.test.ts):
  - 38 tests covering all timing constants
  - Helper function tests
  - Timing consistency validation
  - Scene duration verification (total = 90s)
