feat(i18n, ui): enhance file type filtering with internationalization support

- Updated the file type display logic to utilize i18n for dynamic translations.
- Refactored filter button definitions to include data attributes for improved localization.
- Added new translation keys for various file types and filter options in both English and Chinese.
- Implemented a method to refresh button texts upon language change, ensuring consistent UI updates.
