Apply manufacturing rules per carcass subtype

Set manufacturing rules on each cabinet sub-unit so only that sub-unit's panels change.

1. Manufacturing rules are applied separately for each cabinet sub-unit rather than to the cabinet as a whole.

2. Each rule picks one 'Cabinet sub-unit' from Carcass Excluding Back Panel, Panel, Back Panel, Custom Panel (standalone), Shutter, Shelf and Drawer Fascia, and only panels of that sub-unit change (a Back Panel rule changed only the back panel's price).

3. The rule's applicability can be 'No Condition' (every cabinet), but its criteria keep at least one condition row (an empty row is marked red and Add does nothing), so a rule meant for all panels of a sub-unit still names a condition, for example on the ply or finish thickness or tag.

4. Set each sub-unit's rule individually so the correct rate and SKU mapping apply.
