feat: improve user detail dialog routing in Admin Control panel

- Change from query parameters to path segments for user ID
- Update URL structure from /admin/users?userId={id}&userDetailDialog=true to /admin/users/{id}
- Add route parameter handling with timing control for data loading
- Fix dialog opening race condition by implementing pending user ID logic
- Maintain backward compatibility with existing dialog functionality

Resolves #5833
