Clean prepaid SoT, identity mailbox, public access planes, leaf policy, fleet spawn

Persist account-balance books; edge caches prepaid from books. Add zappier-identity, verae-nats-accounts, verae-jobs-events, verae-access-staff, zapier-decisions. Edge binds loopback; lan-134 stays off; HTTP services prefer local spawn.
