Expand description
Component impls for the TlsSet<InboxId>-shaped components:
AdminListComponent (ADMIN_LIST),
SuperAdminListComponent (SUPER_ADMIN_LIST), and
DmMembersComponent (DM_MEMBERS, immutable).
All three share an identical wire format and trait shape. They
differ only in their ComponentId and the dispatch layer’s
immutability gate (DM_MEMBERS is in the immutable range, so the
dispatch layer rejects Update writes before they reach this impl
— but the impl is still valid as a read path).
