/**
 * A custom hook that retrieves and formats the ETH balance for a given wallet address.
 *
 * This hook uses `wagmi`'s `useBalance` internally and formats the raw balance value
 * into a human-readable string with 18 decimals (ETH standard), along with a rounded
 * version limited to 8 decimal places.
 *
 * It also handles potential balance-fetching errors and returns them in a structured format.
 *
 * @param address - The wallet address for which to fetch the ETH balance.
 * @returns An object containing:
 * - `convertedBalance`: The balance in ETH as a string.
 * - `roundedBalance`: The balance rounded to 8 decimal places.
 * - `error`: An optional `SwapError` object if an error occurred while fetching the balance.
 * - `response`: The original `useBalance` response from `wagmi`.
