feat: make technical contacts optional for all domains

- Remove automatic tech contact assignment from admin contacts
- Set minimum tech contacts to 0 for all registrant types
- Update tests to reflect optional tech contacts
- Keep max tech contacts limit from settings

This change implements the requirement to make technical contacts optional
for all domain types while maintaining the maximum limit from settings.
Previously tech contacts were required for organizations and automatically
copied from admin contacts.
