fix(pitch-deck): Cloud-Hosting 1500 base + 100/customer, fill material costs

- SysEleven: 1500 EUR base (288 cores + managed), +100 EUR/customer >10
- 3rd Party API (Tavily): 45-700 EUR/Mon scaling
- Datenbank-Hosting: 180-900 EUR/Mon scaling
- CDN/Storage/Monitoring: 85-780 EUR/Mon scaling
- Gross Margin now ~80-89% (realistic for AI-SaaS)
