feat(admin): doctor claims audit page + owner_status visibility in doctors list

- DoctorClaimsPage: paginated claim requests (status filter, verification
  method, masked mobile, human-readable failure reason, Jalali dates) +
  manual-transfer modal calling POST /api/v1/admin/doctors/{uuid}/transfer
- DoctorsPage: owner_status filter segment (بدون‌مالک/تصاحب‌شده) + badges
  for unclaimed / pending_transfer rows
- doctorsList API mapping now returns owner_status + source
- route /admin/doctor-claims (admin-only) + sidebar entry
