Review round 1: mesh-mail's real shape has no broker, rollout mint issues its processes, the acceptance test connects with the minted account (issue 1181)

mayIssue no longer requires a module's own broker secret when one of its
processes declares bus: mesh-mail's real manifest has none, its tools
served by the tool runner. rollout mint gained a KindProcess case, so a
process's account rotates the same way every other bus account does. The
release's acceptance test now composes its principals the real way
(inventory.ProcessesOf -> broker.Users -> broker.ComposeAccounts), mints
through the store as module issue does, and sets each connection's own
inbox prefix so replies are not refused; it moved from internal/broker
(which cannot import inventory) to cmd/mesh-controller. Added an
integration test proving the mint, accept and vault hand-off, and that
issuing again rotates the password.
