Submit an offline payment ZK proof for settlement.

Anyone can submit a proof - the submitter doesn't need to be the sender. This allows either party (buyer or seller) to settle when they come online.

The proof verifies:

Prover knows zk_secret such that commitment = Poseidon(zk_secret)
nullifier = Poseidon(zk_secret, nonce) for some nonce
All public inputs match the claimed values

Arguments

proof - The Groth16 proof bytes
sender - The account sending funds (must have registered commitment)
recipient - The account receiving funds
amount - The amount to transfer
cid - The community identifier
nullifier - The unique nullifier for this payment
