docs: record KIOSK cleanup results and verification evidence

Add recent-photo entry points to face recognition and its result page, preserve selection on back navigation, and reuse photo selection and payment flows. Switch face search to v3 with server defaults. Include cropped guidance audio, request and UI coverage, and verification artifacts.
