In-stock rows were toggled to `item_status="ready_invoice"` without
setting `qty_collected`, so the Invoicing page's `min(qty_collected,
quantity)` rule pushed a 0-qty line to QuickBooks for every in-stock
row. The operator couldn't invoice — the goods were physically on
the shelf but the system thought nothing had been received.
Single-row `toggleInStock` and bulk `markInStockReady` now both stamp
`qty_collected = quantity` on the flip. In-stock rows still don't go
through a supplier PO (`purchase_order=""`) — the fix is purely on
the "we have these on our shelves" signal that feeds invoicing.
Backfill: ran `scripts/nss-backfill-in-stock-qty.ts` across the org.
Found 316 stale `in_stock=true` rows out of 324, stamped
`qty_collected=quantity` on each. Idempotent (second run reports 0
to do). ZA10PO26011801 (Master Drilling, M16 rod) and Q202609445
(Denmar Steel — 8 lines including nuts/washers at qty 170) verified
in PB.
Companion fix to the earlier in-stock totals exclusion: the
Invoicing page now gets the full qty for each in-stock row, while the
process-page PO totals still exclude them (since no PO is sent). Both
behaviours line up.
