FIX: Resolve keyboard shortcuts and enhance image preview with i18n support

- Fix keyboard shortcut conflicts in FileViewer.tsx (Ctrl+F, H, ?, Space, A)
- Add comprehensive i18n translations for keyboard shortcuts help panel
- Integrate react-photo-view for enhanced fullscreen image viewing
- Simplify image preview by removing complex toolbar and hover hints
- Add proper error handling and loading states for image display
- Update English and Chinese translation files with new keyboard shortcut terms
