The packing slip report only existed for stock.picking (Delivery Orders),
but this shop ships via fusion.plating.delivery and has no pickings — so
packing slips never rendered for their flow, and the prior auto-generate +
email-notification paths pointed the stock.picking report at a delivery
(wrong model -> blank PDF).
Add a delivery-native variant: report_fp_packing_slip_delivery_portrait +
action_report_fp_packing_slip_delivery_portrait (bound to
fusion.plating.delivery -> shows in the delivery Print menu), resolving the
SO + lines from the delivery job_ref (same pattern as the BoL report) and
reusing the shared styles / address / signoff bits + a sale.order.line
items table. Repoint _fp_generate_packing_slip (dispatch auto-gen) and the
notification attachment to the new report.
Verified on entech: real content (customer, PO, items, PS#) for DLV-30102 —
142KB PDF vs prior blank 12.8KB.
