Each of the 14 section-item dialog files (award→volunteer) had identical
~50-line Create/Update shells (DialogContent + header + form + footer).
Added section-item-dialog.tsx with a SectionItemDialog wrapper that takes
title, icon, onSubmit, onCancel, isSubmitting, submitLabel, singleColumn?.
cover-letter and summary-item use singleColumn=true for their one-column
layout. custom.tsx is untouched (it creates section definitions, not items).
