Einnahmen-Ausgaben view for the Milchbüchlein/simple-accounting case:
- taxReportService.getTaxReport now returns a cost side (loadCosts:
incoming invoices + internal expenses, company- or event-booked,
schema-guarded) plus a summary (income / costs / result, VAT payable)
- declined/duplicate costs excluded; re-billed costs kept (matching
re-bill revenue is counted, so the net is correct)
- CSV + PDF exports gain a Costs section and an income/costs/result
summary; pdf-i18n keys added for all 6 locales (fr/nl/pt/ru machine —
flag for native review)
- frontend tax page renders the summary card, a costs table (company
vs event), and a 'verify with Treuhänder' disclaimer
- tax-report tests cover the cost aggregation + zeroed summary when the
accounting tables are absent; adminCrmAuth test enables the accounting
master flag the route now requires
fr/nl/pt/ru strings are machine-generated and need native review.
