fix(pitch-deck): betriebliche accordion header-first, umsatz labels, annual display

- Betriebliche: category header (sum_row) now renders BEFORE detail rows
- Umsatzerlöse: renamed to Preis/Monat, Anzahl Kunden, Umsatz per tier
- Engine: tier matching via parentheses extraction (handles renamed labels)
- Annual column: quantity=Dec value, price=Dec value (not cumulated)
