Add Photos onboarding step; let pending/rejected users re-edit freely

- New /onboarding/photos step (upload/delete grid, needs >=1 photo to
  continue), inserted as step 2 right after basic info.
- Pending screen gets an "edit your info" entry point into the wizard;
  Rejected screen's edit button now goes there too instead of just
  the read-only profile page.
- Step 1's back button now returns to /home instead of /login when
  the user is already onboarded (was previously always /login).
- Progress bar segments become clickable to jump directly to any step
  once the user is already onboarded.
