Adjacent work: PDF receipts, encrypted blob+share mock, NATS tunnel, SHA256 Zapier action

Around remaining blockers (Zapier login, live Verae): generate PDF receipts
without extra deps; AES-256-GCM object store with tenant isolation and share
tokens; scripts/nats-tunnel.sh to NS1; SHA256 Hash Text local Zapier action;
scripts/test-offline.sh for the no-login suite.

Learned: other-tenant object GET is 403; share token is the mock unwrap path.
