GR/LPO typed-item fix - extract at public_html ROOT.
Bug: creating a Goods Receipt from an imported old-VD LPO, and editing such an LPO
(e.g. adding a delivery date) + saving, failed with "at least one line with a part /
positive Qty required". Cause: imported LPO lines are TYPED items (LPOSUB_SUBITEMID=0,
no catalogue part), and both saves skipped any line with partId<=0 -> no lines -> error.
Fix: keep a line that has a part OR a typed description (LPO save) / any received qty>0
(GR save). Typed receipts record a CRTSTOCKIN linked to the LPOSUB line; the part-stock
bump is a no-op when part=0. No migration. BOTH trees.
