Fix dynamic rulesets not always showing up in force panel + sorting (#59044)

About The Pull Request

These panels used the mutating list of available rulesets based on things like repeatability, not the list of ALL rulesets.

They also used sortList, but this didn't work since these are datums and not names.
Changelog
