Handler invoked after a dialog's content is rendered — and again on every
re-render. Receives the dialog's root element so dynamic behaviour (for
example, updating dependent fields when a dropdown changes) can read and
modify the rendered form. This is the one dialog hook that is inherently a
DOM hook; everything else stays plain-object.
