Pencil icon opens the existing node edit form in the same AJAX modal
as "+ Ajouter une ligne" -- no new form logic, reuses the form_alter
validation/close-on-save already in place for the add form.
Column highlight pairs with the existing row hover (from Gin's global
table CSS) to form a crosshair. Column position is computed logically
(accounting for colspan) rather than via DOM cellIndex, since the
totals row's label cell spans 4 columns and would otherwise misalign
every column after it.
