+@* Generic modal-per-row list editor. The parent owns the List<TRow> (a MUTABLE row VM,
+   because driver contracts are immutable records). This renders a read-only table with
+   Add/Edit/Delete and a modal that edits a CLONED working copy — commit on Save, discard
+   on Cancel. NewRow builds a default VM; Clone copies one for the working copy; Validate
+   (optional) returns an error string to block commit or null to allow. *@
