/**
 * The `InterestRateClient` class provides methods to interact with the interest rate management system
 * of the Aave protocol on the Aptos blockchain. It extends the `AptosContractWrapperBaseClass` and
 * includes functionalities for configuring and calculating interest rates, managing rate strategies,
 * and retrieving rate parameters for assets.
 *
 * @remarks
 * This client is designed to work with the interest rate contracts and provides a high-level API
 * for interest rate operations. The client can be instantiated in two ways:
 * 1. Using the constructor directly with a provider and optional signer
 * 2. Using the static buildWithDefaultSigner method which automatically configures the client with the provider's pool profile account
 *
 * @example
 * ```typescript
 * // Using buildWithDefaultSigner
 * const provider = new AptosProvider();
 * const client = InterestRateClient.buildWithDefaultSigner(provider);
 *
 * // Using constructor directly
 * const provider = new AptosProvider();
 * const signer = provider.getPoolProfileAccount();
 * const client = new InterestRateClient(provider, signer);
 *
 * // Get interest rate strategy for a reserve
 * const strategy = await client.getReserveInterestRateStrategy(reserveAddress);
 * ```
 *
 * @param provider - The AptosProvider instance used to interact with the Aptos blockchain.
 * @param signer - Optional Ed25519Account signer for transaction signing.
