Restructure the API token management interface with a focus on
information density and modern design patterns:
- Replace large card layouts with compact table view for token list
- Add visual statistics cards for total, scoped, and wildcard tokens
- Implement toggle button controls instead of checkboxes for scope selection
- Streamline token creation form with collapsible custom scopes
- Improve visual hierarchy with SectionHeader and ApiIcon components
- Add gradient backgrounds and refined spacing throughout
- Maintain accessibility while reducing overall page footprint
The new design presents all critical information at a glance while
preserving functionality and reducing visual clutter.
