DEV: CSS-only mask

This PR merges the topic-list-item card component into the nextgen theme.

Also does the following cleanup:

* Use template-only ember components
* Use `fire` instead of deprecated `fa-fire` icon
* Lower version requirement for node to 18 to match core
* Add english locale strings for topic status column
* Remove dummy theme settings
