Update dependencies and refactor server configuration: Upgrade @vue/cli and ESLint packages, replace moment.js with date-fns for date handling in eventController, and remove unused HTTPS server configuration in server.js. Additionally, streamline Vue.js build process by removing cache and thread loaders in vue.config.js.
