This commits changes the language for components that aren't used on any themes to be "used/unused" instead of "active/inactive" throughout the new components listing page.
When an installed component doesn't have a description in its locale
files, we should fallback to the description that core has for the
component if it's one of the popular components that core features.
On sites with many components, serializing and rendering all components
in one-go on a page can take quite a bit of time. The new components
listing page that was introduced in
https://github.com/discourse/discourse/pull/32164 currently loads all
components in one-go, so this commit implements infinite-scrolling
pagination for the page to address this performance issue for sites with
many components.
Follow-up to https://github.com/discourse/discourse/pull/31887
This commit introduces a new design for the components listing page, which
is not linked from anywhere in the UI at the moment, but it can be
accessed by heading to the `/admin/config/customize/components` path
directly. We'll make this new design available from the sidebar and
remove the old page once we've tested and validated the new design
internally.
