- on stripe disconnect, the prices on tiers are deleted, which causes the archive/unarchive on them to fail in admin
- this change removes the archive/activate option for such tiers, which will get properly cleaned up once we start removing tiers on stripe disconnect
no issue
- ran [ember-native-class-codemod](https://github.com/ember-codemods/ember-native-class-codemod) to convert the majority of remaining EmberObject based controllers and components to native class syntax using the `@classic` decorator
- skipped older style modal components (`components/modal-*.js`) due to observed incompatibilities in some cases
