adminDid property
Long-term admin DID after this provisioning. Equals clientDid when no admin
rollover occurred (TemplateBootstrap with no adminTemplate); equals the
freshly-minted admin DID when adminTemplate was used or when the ask was
adminRotation. Maintainers that pre-date admin rollover MAY omit this; consumers
SHOULD default it to clientDid for backward compatibility.
Implementation
final String? adminDid;
