Update package dependencies and enhance CSV handling in CMS

This commit updates the version of several packages in package.json and package-lock.json, including downgrading "quill" to 2.0.2 and upgrading "devalue", "diff", "h3", "node-mock-http", "tar", and "undici" to their latest versions. Additionally, it improves the CSV file handling in the CMS by implementing a cache-busting mechanism for fetching data and enhancing error handling during file saving, ensuring more robust data management.
