feat(privacy): surface the customer-data scan above the hardware report

- Move the "Customer data" panel to the top of the data section (above the
  chart iframe); header + customer guess always visible, findings table
  collapsed by default and expandable.
- Add a chart top-notice (above Board/CPUs) summarizing the scan via the
  viewer's standard NoticeTitle/NoticeBody - interim until chart custom panels.
- Allowlist ieisystem.com (IEI = Inspur brand infrastructure).
- Add chart-custom-panels-spec.md: a reusable, versioned contract proposal for
  host-supplied panels across every app embedding reanimator/chart.
