i18n: Refactor translation management tools and add ignore feature for dynamic resources

- Updated README.md to reflect changes in translation management tools and added ignore mark feature for dynamic resources.
- Created Chinese translation guide for the translation management tools.
- Created English translation guide for the translation management tools.
- Enhanced translation-cleaner.py to skip keys marked with /*keep*/ during cleanup.
- Improved translation-manager.py to create backups only when updating keys interactively.
- Updated zh_CN.json with new translations and added ignore marks for dynamic values.
