797 client - Filter nested cluster element slots by element's own name

The clusterElementClusterElementTypes map is keyed by the cluster
element's own name (the third segment of its type, e.g. 'search',
'vectorStore'), not by the parent slot key (e.g. 'tools'). Both the
placeholder-creation recursion and the handle renderer were passing the
parent slot key and falling back to showing every type. Forward the
element's own name so slot filtering actually applies.
