The PDF export was an unformatted list of doc.text() lines and only showed real cash movements (payment type). Rebuilds it as a proper two-section report: a branded header band, a bordered/zebra-striped table with colored amounts and bold running balance for cash movements, and a second "Forderungen" section listing fine/levy/fee entries created in the period with their own total. Tables paginate across pages and every page gets a footer with page numbers. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
