feat(pitch-deck): Use of Funds computed from fp_* spending data

Use of Funds pie chart now shows actual spending breakdown from fp_* tables
(months 8-24) instead of manually set percentages:
- Engineering & Personal: from fp_personalkosten
- Vertrieb & Marketing: from fp_betriebliche (marketing category)
- Betrieb & Infrastruktur: from fp_betriebliche (other categories)
- Hardware & Ausstattung: from fp_investitionen

Falls back to funding.use_of_funds if fp_* data not yet loaded.
