feat(mobile-app): redesign wallet generation UI with overlay mask and countdown

- Replace full-page loading with overlay mask design
- Add 100-second countdown timer with circular progress indicator
- Show placeholder data (******) in mnemonic and address cards during loading
- Display "正在进行钱包的安全计算" message with security icon
- Implement error overlay with retry button
- Disable copy buttons and action buttons during loading state
- Maintain consistent UI layout between loading and ready states
