Incoming expense refunds (positive amount on an expense category) previously
booked with inverted debit/credit — crediting the bank and debiting the expense
account — which both imbalanced the book and reported negative bank flow.
getCategoryAccountMapping now detects amount > 0 on expense categories and
returns the reversed mapping: debit 1930, credit expense account, with 2641
as vatCreditAccount so ingående moms is correctly reversed on the VAT line.
The VAT line description is "Återföring ingående moms X%" rather than the
income-side "Utgående moms" label.
