feat(onboarding): add /start mode chooser, fix pilot-profile-setup UX

- Fix missing icon for the free-tier/self-host pricing option
- Make selected cards visually obvious (checkmark badge, stronger border)
- Add Back navigation between onboarding steps
- Network-experience screen: button reads "No, not yet" instead of an
  ambiguous "Continue" when nothing is selected
- classroom-introduction reverts to Classroom-only content; the
  Classroom/Live ATC chooser moves to a new /start page instead
- Remove the "Skip to Classroom" button in favor of a subtle text link
- New /start page: choose Classroom or Live ATC after login (when
  there's no specific redirect target) or right after finishing
  onboarding. Shows a "start with Classroom" hint only for first-time
  arrivals from pilot-profile-setup. Live ATC is locked for 24h after
  registration.
