Fixes #37995 - High memory rendering Arf Report index page

[hao-yu]

Avoid using includes() with nested associations and "order by" together. Otherwise, includes() will use join tables instead and Rails somehow create many objects and high memory consumption.

For more information, please refer to https://projects.theforeman.org/issues/37995
