feat(desktop): adjust nest quantities from the drawing library dialog

After adding library drawings the operator had to close the dialog to see what
the nest now needed, and fixing a quantity meant leaving it for Edit Drawing
one part at a time. The new In This Nest tab lists the nest's drawings (cutoffs
excluded) with their library revision and required, nested and remaining
quantities, refreshes after each add, and edits Required in place.

An edit applies to the nest immediately, like an add, and the nest window
refreshes its drawing list when the dialog closes. Out-of-range values are
refused both when the cell is validated and when they are applied, because
DataGridView only validates on leaving the cell and EndEdit commits without it.
