feat: Add language support and ID comparison feature

- Introduced a new language display in the banner, showing the current language (Simplified Chinese or English).
- Added a function to display a comparison of old and new IDs after configuration updates.
- Implemented a new function to read existing configuration from a file.
- Updated success and warning messages to use distinct colors for better visibility.

This commit enhances user experience by providing language context and ID comparison during configuration updates.
