fix: draw the inline value editors over the tree, so their caret shows

TreeList fills a background quad for every visible row, including the selected
one it leaves a value-cell hole in. The inline editors were painted before it,
so an editor's box, border and caret all landed under that quad — only its text
survived, because the engine draws every label after all geometry. The control
looked absent and had no caret while still taking input.

They float over the tree's rows, so they are painted after both panes now.
