1. Low stock: use min_stock_level (not reorder_point), eager-load inventoryLevels
2. Inventory movements: reference is a morphTo — show class_basename#id instead of raw object
3. Product sales: pos_transaction_items has item_type/item_id (not product_id)
4. POS transactions: relationship is processedBy (not user), field is receipt_number
5. Collect payment wizard: only search participants with outstanding invoices
