feat: Redesign job editor with multi-row parts and unified cut list results

- Part form now supports adding multiple parts at once via a table with
  add/remove row controls; edit mode stays single-row
- Shape and size dropdowns lock when editing an existing part
- Results tab replaces split in-stock/purchase cards with a unified table
  per material showing source badges (Stock/Purchase) for each bar
- New Purchase List card summarizes materials to order with quantities
- Print styles use repeating thead headers per material for multi-page
  cut lists; large cards can now break across pages
