feat(pitch-deck): add pitch version selection to investor invite form

- Version dropdown on the invite form shows all committed versions
- Selected version is assigned to the investor at creation time (no separate step needed)
- API validates version is committed before upserting
- Leaving the dropdown empty keeps any existing assignment (COALESCE behavior)
- version_id included in audit log
