* UX: Admin setting page consistency - Group permissions (#30528)
Followup c2282439b3 and
21470e4afd
Adds a new "Group permissions" page and group_permissions site
setting area, which shows every single group-based site setting
in the app and core plugins.
Also adds a "trust_levels" area to show on the already moved
admin "Trust level" settings page, since that previously was
showing a mix of trust level settings and allowed group settings.
* DEV: Review fixes
This plugin is only useful for developers, however, making it core allows us to centralize any component modification in one commit.
This integration also adds a new site_setting: `styleguide_admin_only` which allows to enable a styleguide on a live site while restricting visibility to admins only.
By default, styleguide is disabled.
