Fix: Remove duplicate financing cost in Project Cost Breakdown table

The financing cost (IDC + upfront fees) was being displayed both as a separate
line item AND included in the total calculation, causing the Total Project Cost
to be inflated by the financing amount. This fix removes the separate financing
row from the breakdown table while keeping the correct total calculation.
