- Remove StatusBadges component (badges for authenticated, connected, groups)
- Remove ActionButtons component
- Create individual button components:
  - SessionStatusButton: handles session status check
  - ProfileButton: navigates to user profile
  - LogoutButton: handles user logout
  - LoginButton: reloads page to trigger login
- Update app.vue to use new individual button components
- Improve code quality with better component separation and reusability
