Issue every node's memberships when it is composed, so a module taken in with a new state is not refused it (issue 249 met again, issue 1945)

Release 6 removed the push (788fb681), and with it the only writer of the
memberships on ASSIGNMENTS. A module taken in since kept the membership the
old push last issued: mesh-delivery-gate, taken in with the state
"conditions" at 20:33 on 2026-10-25, was granted its bucket on the bus and
refused it by novox's tool runner every second, which keeps a module to its
membership (node-tools internal/bus/state.go issuedState).

A node's composition pass now issues the membership of each module assigned
to it, from the same records the grants are composed from, with the node's
private-network addresses and received contributions, before its
compositions are written. Only one that differs from the one last issued is
published, and only over that one (issues 930, 934). The memberships' stream,
every declared bucket and log are asserted first; the root-free judgement
runs only when a held seat promises a verified sender.

NATS-native piece moved (research 072, 03-domains, mesh-grants): the
membership is issued again by the take-in's pass, from the grants' records,
the step before mesh-grants takes both over.
