Display DNS records correctly

Display type, full name, value, purpose, required status, current status, and description. Preserve multiple verification methods. Offer a copy button per value, but do not convert full names to @ in stored data.

dns-table.ts

const rows = domain.records.map(({ type, name, value, purpose, required, status }) => ({
  type,
  name,
  value,
  purpose,
  required,
  status,
}));

Explain that registrar UIs may automatically append the zone and that proxying can interfere with provider checks.
