`add-button-inner` previously rendered the trailing add-sibling
button only when the rendered entity was a page or on mobile, so a
block opened via "Open in sidebar" or rendered as an embedded root
had no discoverable way to append a child on desktop.
Destructure `block?` (already set by `page-blocks-cp` to
`(not (db/page? block))` when building hiccup-config) and add it to
the render predicate so block-rooted views surface the button too.
