fix(pitch-deck): all financial slides now read from fp_* tables via useFpKPIs

New shared hook: useFpKPIs — loads annual KPIs from fp_guv/liquiditaet/personal/kunden.
Replaces useFinancialModel (simplified model) for KPI display on all slides.

Slides updated:
- CompetitionSlide: "110 Gesetze" → "380+ Regularien & Normen"
- BusinessModelSlide: ACV + Gross Margin from fp_* (was useFinancialModel)
- ExecutiveSummarySlide: Unternehmensentwicklung from fp_* (was useFinancialModel)
- FinancialsSlide: KPI cards from fp_* (ARR, Customers, Break-Even, EBIT 2030)

All slides now show consistent numbers from the same source of truth (fp_* tables).
