/**
* 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`)
*
* [Access Keys Specification](https://docs.tempo.xyz/protocol/transactions/spec-tempo-transaction#access-keys)
