🌐 feat(i18n): add internationalization support for TwoFASetting component

- Add comprehensive i18n support to TwoFASetting.js component
- Add all required English translations to en.json for 2FA settings
- Update component to accept t function as prop and use translation keys
- Fix prop passing in PersonalSetting.js to provide t function
- Maintain all existing UI improvements and functionality
- Support both Chinese and English interfaces for:
  * Main 2FA settings card with status indicators
  * Setup modal with guided steps (QR scan, backup codes, verification)
  * Disable 2FA modal with impact warnings and confirmation
  * Regenerate backup codes modal with success states
  * All buttons, placeholders, messages, and notifications
- Follow project i18n conventions using t('key') pattern
- Ensure seamless language switching for enhanced user experience

This enables the 2FA settings to be fully localized while preserving
the modern UI design and improved user workflow from previous updates.
