Survivor side (4/4): truthful ring confirmation + 'Who owns it?'

- TrackerRinger now reads the DULT/Find My indication: reports 'Ringing confirmed' on the tag's response, or (after a 4s wait with no confirmation) 'sent, but the tracker didn't confirm - it only rings when separated from its owner'. AirTag still confirmed by its self-disconnect. No more over-claiming from a bare write-ACK.
- 'Who owns it?' on the tracker detail: guidance to tap the tag with NFC and let the phone open the owner's masked contact page (works via Android's built-in NFC dispatch; VIGIL stays offline).
Release 0.1.11 — completes the survivor-actionability work (safety + onboarding, history + export, trail, ring confirmation + owner info).
