/**
 * Generates an authorization URL for either login or webhook requests,
 * including scopes, state, and redirect URIs. This URL can be used in OAuth2
 * authentication flows, such as logging in or connecting a webhook.
 *
 * @function
 * @param {Record<string, any>} tinyCfg - The configuration object containing the app's OAuth2 settings.
 * @param {Record<string, any>} jsonState - The state object to be encrypted and passed in the authorization URL.
 * @param {Record<string, any>} tinyCrypto - The crypto object used to encrypt the state.
 * @param {string} type - The type of the request, which determines the URL generation process.
 *                         Can be `'login'`, `'login_command'`, or `'webhook'`.
 *
 * @returns {string} The generated authorization URL for OAuth2 authorization.
 *
 * @example
 * const authUrl = authURLGenerator(tinyCfg, jsonState, tinyCrypto, 'login');
 * console.log(authUrl);
 *
 * @example
 * const webhookAuthUrl = authURLGenerator(tinyCfg, jsonState, tinyCrypto, 'webhook');
 * console.log(webhookAuthUrl);
