API updates to better support team spaces

This post details API updates to better support Dropbox's evolving team space functionality. New features include `distinct_member_home` and `team_shared_dropbox` flags on user and team feature endpoints, a `team_member_root` namespace type, and a `root_folder_id` field in `TeamMemberProfile`. It also outlines behavioral changes regarding team folder sharing, root namespace types, and how to list team content using new API endpoints like `/2/team/namespaces/list`. The goal is to enable applications to correctly identify and interact with updated team space configurations, ensuring compatibility with new privacy and scalability improvements.
