- Split the 1554-line PersonalSetting.js file into smaller, maintainable components
- Created organized folder structure under personal/:
  - components/: UserInfoHeader for shared user info display
  - tabs/: ModelsList, AccountBinding, SecuritySettings, NotificationSettings
  - modals/: EmailBindModal, WeChatBindModal, AccountDeleteModal, ChangePasswordModal
- Refactored main PersonalSetting component to use composition pattern
- Improved code maintainability and separation of concerns
- Added collapsible prop to ModelsList tabs for better UX
- Fixed import path for TwoFASetting component in SecuritySettings
- Preserved all existing functionality and user interactions

This refactoring reduces the main file from 1554 to 484 lines and makes
the codebase more modular, testable, and easier to maintain.
