Visibility into Available Function Module Node Licenses During Tenant Creation

When creating or editing tenants in an MSP-enabled licensing configuration, administrators currently cannot see how many Cross-domain Monitoring, Automation, or IT Business Analytics nodes have already been assigned to other tenants versus how many remain available. This enhancement would display the assigned and remaining node counts for each function module directly within the tenant creation and edit screens. Providing this visibility would help administrators allocate node licenses accurately across multiple tenants and avoid over-provisioning or under-provisioning during setup.
