We wanted to switch to a settings menu that stays open to the right of the editor rather than a popover that blocks all other interaction with the post to solve two use-cases:
1. when editing it's fairly common to select some text from the post contents when setting excerpt and meta data text, with the previous design not letting you scroll or select whilst the menu got in the way of that
2. having the menu open with meta data visible before publishing can help you see everything is set as you want and help you feel confident when publishing/sending content

- removed `psmRedesign` labs flag
- swapped labs component/css for main component and deleted labs component
- cleaned up now-unused `ui.showSettingsMenu` property and related actions/classes
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
