feat(pitch-deck): Pricing slide, GuV hierarchy, Problem/Solution cards, engine fixes

- BusinessModel → Pricing: remove Unit Economics, fullwidth tiers
- GuV: major sums (EBIT, Rohergebnis, Jahresüberschuss) larger font + border
- Engine: compute Rohergebnis, dynamic financing row matching
- Problem slide: amber/orange "Die Konsequenz" card
- Solution slide: larger Compliance Optimizer card
- DB patch: Stammkapital, 2. Finanzierungsrunde 500k, GuV sort order
