Thrown when Wallet.createCash funds the note but its send call
fails after the transaction may already have been submitted.
The whole value of the note lives in cash: it carries the private key that
controls the funded output. If send committed and this error is discarded,
the sats are stranded at an address only this token can reach. Callers that
cannot rule out a post-submit failure must persist cash — passing it to
Wallet.claimCash recovers the funds whether or not the send landed.
