Base64-encoded all-signatures-zeroed wire form of the create_escrow
transaction CFX built at API prepare time. Persisted so the
submitCreateEscrowTransaction activity can tamper-check the
client-signed transaction by zeroing its signatures and byte-comparing
against this. Only set on rows created via the public POST /v1/escrow-transfers endpoint — backfilled rows do not have it.
