Summary:

The code changes in this pull request primarily involve updates to the Bootstrap CSS and JavaScript libraries used in the application. The changes include updating the Bootstrap Reboot CSS, Popper.js, and Bootstrap Grid CSS files to the latest versions. These updates are generally positive from a security perspective, as they help ensure the application is using the latest versions of these libraries, which typically include bug fixes and security improvements.

However, it's important to thoroughly review and test the changes to ensure they do not introduce any unintended consequences or security issues. Updating to a new major version of a library like Bootstrap can sometimes introduce breaking changes, so the application should be thoroughly tested to ensure the updated files do not cause any visual or functional issues. Additionally, developers should continue to follow secure coding practices when integrating these libraries, such as properly sanitizing and validating user input and avoiding potential DOM-based vulnerabilities.
