Complete Chinese comment cleanup in File Manager components

- FileManagerModern.tsx: Translate all Chinese comments to English, replace hardcoded text with i18n
- TerminalWindow.tsx: Complete translation and add i18n support
- DiffWindow.tsx: Complete translation and add i18n support
- FileManagerOperations.tsx: Complete translation
- Fix missed comment in FileManagerGrid.tsx

All File Manager components now have clean English comments and proper internationalization.
Follow Linus principles: simple, direct, no unnecessary complexity.
