plugins/runcommand: use ColumnLayout for ListView

The ListView displaying the configured actions currently directly uses a
label that is made multi-line by including a newline. As a consequence,
eliding the text does not work properly and there is a visual clash with
the included action button. It also means that there is a rather
pointlessly translatable string that is just there for UI logic.

This change modifies the delegate to use a ColumnLayout instead, which
enables correct eliding of the labels and more cleanly separates layout
and content concerns.
