"""Status-code matrix for every management route that admits a team admin today.

Each route is called as a proxy admin, an admin of the target team, a plain member, an admin of another team
and a teamless user. It is called again on a team that belongs to an organization, as an admin of that
organization and as an admin of another organization. The expected codes pin current behaviour so the shared
team-admin gate can prove parity.
