/**
 * Makes an HTTP request using the `fetch` API.
 *
 * This function sends an HTTP request based on the provided `RequestConfig` object and handles the response.
 * If the request fails (i.e., the response status is not OK), it calls `handleError` with the error message.
 *
 * @param {RequestConfig} config - The configuration object containing the URL, request method, body (optional, stringified JSON), and optional headers.
 * @returns {Promise<Response>} A promise that resolves to the response object.
 * @throws {AppError} Throws an `AppError` if the response status is not OK.
 *
 * @example
 * const config: RequestConfig = {
 *   url: 'https://api.example.com/data',
 *   method: 'GET',
 *   body: JSON.stringify({ 'first-name': 'Estarlin' }),
 * };
