Add photo upload as a real onboarding step

Photos are now step 2 of onboarding (right after basic info) instead
of only being manageable from the profile page later. Uploading still
goes through the existing /profile/photos endpoint; the new
POST /onboarding/photos just confirms at least one photo exists and
advances the step counter. Renumbered the OnboardingStep enum
accordingly (9 steps total now).
