These two come from the upstream Phoenix generator and are worth keeping for
future data/admin screens, so they stay rather than being deleted as dead code.
The note also records why they look unused but aren't pointless: the collections
already in the UI are hand-rolled (editor_dashboard_live's drafts/scheduled rows
are bordered divs; Blogex.Components.post_index renders post previews and tag
lists itself). That is the fact a future reader needs before either deleting
these or writing yet another bespoke list.
