C3: the callers of mesh-broker's four reads, mesh-config's renames, mesh-vault's retire and node-engine's seat-list verbs are lists

mesh-broker list, show, check, orphans and mesh-config renames name invokers; mesh-vault retire names
seat:mesh-config; node-engine seat-list names persons and healers, seat-list-again the operator and the
healers. mesh-broker create, apply, recreate and drop keep their text: the design names no form for them.

Builds: design 47 G §336, §392, §204
