feat(reports+configurator): invoice PDF uses macro; x_fc_part_catalog_id on account.move.line (Sub 2 Task 19)

Invoice PDF (portrait + landscape) now collapses SKU + Description into
a single Part column rendered via fusion_plating_reports.customer_line_header,
so customer-facing invoices print the customer's part number (with
revision) instead of the internal service SKU.

To feed the macro on invoice lines, add x_fc_part_catalog_id to
account.move.line and override sale.order.line._prepare_invoice_line so
the part reference propagates automatically when an SO is invoiced.
