chore(examples): fix read permission in auth example (#12403)

The return value of the `adminsAndUser` method was not a proper Query to
limit the read scope of the read access. So users could read all user
data of the system.

Alongside I streamlined the type imports (fixes #12323) and fixed some
typescript typings. And aligned the export of the mentioned to align
with the other access methods.
