style: implement left-right layout for export statistics cards

- Change to left-right layout: left side statistics info, right side icon
- Follow TemplateMatchingResultStatsPanel design pattern
- Use white background with subtle shadow and border
- Add percentage calculations for success/failure rates
- Add average file size calculation
- Use larger icons (w-8 h-8) with opacity-60 for visual balance
- Include subtitle information for better context
- Match the exact layout structure used in project statistics

fix: correct re_export_record command parameters
- Add newFilePath parameter using file dialog selection
- Fix parameter naming to match backend expectation (newFilePath)
- Implement proper file selection dialog for export path
