/**
 * Team Service — unit tests
 *
 * Tests the in-place workspace member creation flow (no email invites):
 *   1. signUpInWorkspace → creates user + workspace member
 *   2. updateWorkspaceMember → set name
 *   3. updateWorkspaceMemberRole → assign role
 *   4. (optional) updateAgent → link SIP seat
 *
 * Platform GraphQL + SessionService are mocked.
