Explore how we might implement team structures and privileges

# Team management

## Context

Service owners, program administrators, form builders, and developers can create a team structure and privileges that make sense for the following flows:

- [ ] Sharing a form for testing and feedback
- [ ] Generating and using an API key
- [ ] Publishing forms
- [ ] Adding and managing team members

No files, tests, or entry points are identified in the issue. Start by mapping the four listed flows—form sharing, API keys, publishing, and team-member management—and define the team structure, privileges, and completion criteria for each before implementation.
