Subject: [PATCH] Fix rounding calculation to use real values instead of
 rounded

- Added debugging to TD line query to see why VAT amount is 0
- Fixed fallback logic to use formatAmountReal() instead of formatAmount()
- When TD line has 0 VAT amount, now uses real difference (0.90) instead of rounded (1.00)
- Added logging to track TD line query and results
- Should now show 0.90 instead of 1.00 in rounding entry
