Setting post visibility to a label results in undesirable and confusing behaviour with no good way to manage access long-term. Coupled with products being limited to a single product for now we're reverting the UI back to the "Public", "Members", and "Paid" options.
https://github.com/TryGhost/Team/issues/581
The API now supports `posts.visibility` being an NQL string as well as the special-case `'members'` and `'paid'` values so the post settings menu visibility select needs to be updated to reflect that.
- swapped visibility dropdown for two radio buttons, "Public" and "Members-only" which uses the `<GhMembersSegmentSelect>` component
- updated post model to use a `visibility-string` transform
- converts `members` and `paid` to/from the NQL equivalent for correct display in the segment select
- updated post model with two additional properties `isPublic` and `visibilitySegment`
- `isPublic` helps with the radio button display
- `visibilitySegment` allows fallback to the default content visibility setting when set to public
- added validation for `post.visibility` so we can show an error and skip saving when members-only is selected and the segment select is cleared
- deleted the now-unused `<GhPsmVisibilityInput>` component
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
