Implement team-based organization for projects with role-based access control:

- Add team CRUD, membership, and projects API endpoints

Frontend:

Security:
- Team role hierarchy: owner > admin > member

- Self-modification prevention for role changes
- Email visibility restricted to team admins/owners
- Slug validation rejects consecutive hyphens
Tests:
