Enforce order of enum members from API

In some lists and selectors (e.g. in guide selection form, the guide subclass selector), the order of the items is based on the order of the members of the enum generated by graphql-codegen (alphabetical order actually), which can sometimes be not fully appropriate (e.g. Other can be placed before other members rather than at the end).

Enforcing this order would allow for more coherency/meaningfulness.
