G-catalog-B 7: a transfer dropped by hand is recorded through mesh-hand-acts first

registry_incoming, npm_incoming and go_incoming dropped a transfer by hand with only a log line. Each
drop now records its hand act through the seat mesh-hand-acts before anything goes, as nats_requests
does; an act not recorded leaves the transfer open. distribution's manifest invokes the seat.
