Validate and freeze an account snapshot, including a non-small-order, prime-order
Ed25519 key and its derived address. The nonce is canonical decimal u64 account
derivation data, not a transaction nonce. Rejects extra fields and noncanonical
values rather than normalizing them; malformed input throws code -32602.
