// =========================================================================
// customer_po_lines — one record per line item on an incoming customer PO
// =========================================================================
//
// Splits the `parsed_lines` json blob on a `customer_pos` record into
// individual rows. n8N writes these after extracting SKU, qty, price from
// the customer's PDF. The stock-decrement node reads from here.
//
// Note: `app.findCollectionByNameOrId` is wrapped so this migration applies
// even if `stock_items` isn't present in the local DB. In production (hosted
// PB), `customer_pos` and `stock_items` both exist.
// =========================================================================
