ci: update Node.js requirement and improve code consistency

Updated the README to require Node.js 18+ and added Docker usage instructions. Refactored util/client-sign.js for consistent code style and improved variable naming. Fixed the login_cellphone module to use 'weapi' in createOption. Removed deprecated code from server.js and improved CORS header formatting. Minor fix in util/request.js for user agent selection.
