Merge pull request 'Release 2026.9.30.2' (#140) from release/2026.9.30.2-pr into main

queue.count, user.count and domain.count count the whole cluster, and
only the node with the metrics-calculation role works them out. Every
node still stored them. On the others the queue gauge only moves with
local queue events, so it had drifted below zero (production: node 0 at
18,446,744,073,709,551,596, node 1 at ...613, i.e. -20 and -3), and
the account and domain counts stayed at 0. A reader taking the latest
reading got whichever node wrote last.

sample() now takes whether the node calculates them and leaves them out
otherwise. A unit test covers both cases.
