Create a new child tenant under an MSP parent. The parent is specified via parentTenantID in the request body; the authenticated caller must have MSP-admin permission on that parent.
The type field should be set to MSP_CUSTOMER for child tenants managed by the MSP parent.
New child tenants are created in the ACTIVE state. Use the update endpoint to suspend (INACTIVE) or reactivate later.
After creation, use the MSP Tenant Settings endpoints to configure feature access for the child.
See MSP Customer Management for detailed MSP administration guidance.
