feat(pitch-deck): milestones update, Serverkosten formula, material/liquidität fixes

- Milestones: correct dates + events (DPMA, domains, RAG, EUIPO, GmbH)
- Serverkosten: 2000 base + max(0, customers-10)*250 (first 10 included)
- Materialaufwand: cleared, info placeholder
- 2. Finanzierungsrunde: renamed, sort order fixed
