🎨 UI/UX: Replace emoji icons with Semi UI components and enhance card design

BREAKING CHANGE: Replace all emoji icons with Semi UI icons in statistics cards

- Replace emoji icons with corresponding Semi UI icons:
  - 💰 -> IconMoneyExchangeStroked
  - 📊 -> IconHistogram
  - 🔄 -> IconRotate
  - 💲 -> IconCoinMoneyStroked
  - 🔤 -> IconTextStroked
  - 📈 -> IconPulse
  - ⏱️ -> IconStopwatchStroked
  - 📝 -> IconTypograph

- Add Avatar component as circular background for icons
  - Implement color-coded avatars for each statistic card
  - Set avatar size to 'medium' for better visual balance
  - Add appropriate color mapping for each statistic type

- Adjust layout spacing
  - Reduce top margin from mb-6 to mb-4 for better vertical rhythm
  - Maintain consistent spacing in card layouts

- Import necessary Semi UI components and icons
  - Add Avatar component import
  - Add required icon imports from @douyinfe/semi-icons

This change improves the overall UI consistency and professional appearance by adopting Semi UI's design system components.
