  Partner GRN: lock purchase before quantity check; block re-billing of billed orders
  
  - scanSerialized/scanNonSerialized lock the purchase row (refresh FOR UPDATE) and sum GRNed qty with
  FOR UPDATE before checking against billed qty, so two concurrent GRNs of one invoice can't both pass
  - Serialized GRN rejects a line carrying more IMEIs than its billed quantity (double-billed line)
  - acceptOrders validates billing state; billing re-checks orders under FOR UPDATE so a second click
  can't bill an already billed order
  - Scheme IN skips inventory rows with initial quantity 0 (voided duplicate GRN rows)
  - Includes an empty-list guard in selectWarehouseIdsByInvoiceNumbers from a parallel change
