AZ202: No user type

Every policy declares type user = schema.table: the people who sign in, whose ids authz.act_as('user', id) takes.

Reported when the policy is compiled: rowfence check, the editor, rowfence dev.

The mistake

app role app_user
type folder = app.folders
  can view = signed_in

line 1: declare the user type, e.g.: type user = app.users [AZ202]

Fixed

app role app_user
type user = app.users
type folder = app.folders
  can view = signed_in
