postWalletByIdSign method
Produces a secp256k1 signature from one of the caller org's wallets over a 32-byte digest, through whichever custody backend that wallet uses.
Produces a secp256k1 signature from one of the caller org's wallets over a 32-byte digest, through whichever custody backend that wallet uses. Give it either a digest (32 bytes as hex, signed verbatim) or a message (hashed with Keccak256 first) — exactly one is required. The private key never leaves its backend: KMS custody opens the sealed key in-process, MPC custody produces a threshold signature on the ring. The answer carries the digest that was signed alongside the signature, so a caller can verify what it got.

// When a remote server returns no body with a status of 204, we shall not decode it.
