How to Fix BR-CO-10: BT-106 vs sum(BT-131)

The subtotal (`LineExtensionAmount` / `BT-106`) in the invoice summary does not exactly equal the mathematical sum of all individual line item net amounts (`BT-131`). Even a €0.01 floating-point rounding difference from Excel, Stripe, or OCR triggers a fatal rejection.
