- perform a paid members list query with a limit of 1 when the modal is displayed if the post is set to members only, then use the pagination meta data to get a total number of members
- display a spinner and disable the confirm button whilst the count query is in progress
- does not display any counts for users with the Editor role as they do not have permission to list members

- Updates error messages incorrectly pointing to invalid mailgun config to show more generic error

no issue
Keeps component JS backing files and template files in the same directory which avoids hunting across directories when working with components. Also lets you see all components when looking at one directory, whereas previously template-only or js-only components may not have been obvious without looking at both directories.
- ran [codemod](https://github.com/ember-codemods/ember-component-template-colocation-migrator/) for app-level components
- manually moved in-repo-addon component templates in `lib/koenig-editor`
- removed all explicit `layout` imports as JS/template associations are now made at build-time removing the need for them
- updated `.embercli` to default to new flat component structure
