Collapse the SKU and Description columns in both the portrait and landscape sale-order PDFs into a single Part column rendered through the shared customer_line_header macro, so customer-facing quotes and confirmed orders print the customer's part number (with revision) instead of the internal service SKU. Updates column widths, section/note colspans, and the conditional col_count used for the landscape template's optional discount column to reflect the collapsed header.
