A reference application for a third-party author: its own module, and a
require list that names go-admin-core and nothing else. The point of the
example is that constraint - an application that reaches for the host
cannot be installed through a module proxy at all, because `go-admin` has
no dot in its first path element and a replace directive is ignored
outside the main module.
Two tables rather than one, because a single-table example proves only
what the generic CRUD actions already proved. The interesting question is
whether the contract surface holds up for business that spans tables.
The table names carry an app_ prefix: "order" is a reserved word, and
Permission() interpolates the table name into raw SQL without quoting.
