/**
 * ScVal encoding helpers for the Mercury indexer backend.
 *
 * The hosted passkey-indexer returns fully-decoded signer JSON, so the only
 * on-chain encoding the backend still needs is the contract `SignerKey` ScVal —
 * for the temporary-signer eviction probe (`contractDataExists`) and the
 * reverse-lookup on-chain confirmation (`getSigner`). Both go through the
 * contract Spec built from a throwaway client.
