test(project): cover costing and billing roll-ups

Covers the sales/billing roll-up (total_sales_amount, total_billed_amount,
gross margin) via the whitelisted update_costing_and_billing, and
consumed-material cost from a project-linked Stock Entry issue. The
purchase-cost roll-up is already covered by the Purchase Invoice tests.
