/**
 * Checks whether a given email address already exists via the `/ajax/contact-email` endpoint.
 *
 * The underlying API is expected to return a JSON object containing:
 * - `exists`: `1` if the email exists, `0` otherwise
 * - `error`: `1` if an error occurred, `0` otherwise
 * - `message`: an optional error message when `error === 1`
 *
 * This function normalizes that response to an object with:
 * - `exists`: a boolean indicating whether the email exists
 * - `error`: an optional string containing an error message, if any
 *
 * On network or unexpected errors, it returns `{ exists: false, error: 'Failed to check email' }`.
 *
 * @param {string} email - The email address to check for existence.
 * @returns {Promise<{ exists: boolean; error?: string }>} A promise that resolves to the normalized
 *          result of the email existence check.
