feat(quota): enhance QuotaSection with improved view mode handling and refresh functionality

- Introduced effective view mode logic to manage 'paged' and 'all' views based on file count.
- Added a warning for too many files when in 'all' view, prompting users to switch to 'paged'.
- Updated refresh button to handle loading states more effectively and provide clearer user feedback.
- Enhanced UI with new translations for view modes and refresh actions.
- Adjusted styles for better alignment and spacing in the view mode toggle and refresh button.
