Subject: [PATCH] feat(desktop): slim the set editor to drawing, material,
 quantity and note

The member grid shows one Material column (name, grade, thickness and
units, such as "Steel A36 0.25 in"), Qty and Note; Cut type appears only
when the set mixes cut types. Move Up/Down are gone: member order only
breaks ties (materials are grouped and sorted on release, nests list
drawings by name), and the stored order is kept as it was. The dialog
opens at 1040 px instead of 1264, with the library pane unchanged and
still resizable.
