/**
 * Key authorization for provisioning access keys.
 *
 * Access keys allow a root key (e.g., a passkey) to delegate transaction signing to secondary
 * keys with customizable permissions including expiry timestamps and per-TIP-20 token spending
 * limits. This enables a user to sign transactions without repeated passkey prompts.
 *
 * The root key signs a `KeyAuthorization` to grant an access key permission to sign transactions
 * on its behalf. The authorization is attached to a transaction (which can be signed by the access
 * key itself), and the protocol validates the authorization before storing the key in the
 * AccountKeychain precompile.
 *
 * Key authorization fields:
 * - `address`: Address derived from the access key's public key (the "key ID")
 * - `chainId`: Chain ID for replay protection (0 = valid on any chain)
 * - `expiry`: Unix timestamp when the key expires (undefined = never expires)
 * - `limits`: Per-TIP-20 token spending limits (only applies to `transfer()` and `approve()` calls)
 * - `type`: Key type (`secp256k1`, `p256`, or `webAuthn`)
 *
