refactor(links): extract sort menu and fix sort logic

- Extracts dropdown sort menu into separate DashboardLinksSort component
- Fixes incorrect sort order for newest/oldest links
- Adds internationalization support for sort options
- Updates QR code download button size for consistency
- Adds helpful tooltip about sort limitation for loaded links

The sort logic was reversed where newest/oldest were concerned, this fixes
that while making the sorting feature more maintainable through component
extraction.
