fix(pitch-deck): engine uses dynamic row matching for renamed labels

- Engine no longer hardcodes financing row labels — matches by row_type
- Handles renamed WD rows (Wandeldarlehen Investor/L-Bank, Stammkapital)
- fp-patch: all pending WD fixes (labels, investments, materialaufwand, pos3)
- Bestandskunden annual column shows Dec value (point-in-time)
