Subject: [PATCH] Fix VAT credit scenario balancing logic

- Main balancing entry now uses rounded amount (formatAmount) for proper accounting
- Rounding difference goes to 658000/758000 with real value (formatAmountReal)
- Fixed fallback logic to handle both VAT debit and credit scenarios correctly
- VAT credit: rounded amount on 4456700, real difference on 658000
- VAT debit: rounded amount on 4455100, real difference on 758000
