Rebuild and deploy main

PR Summary

Upgrade of script formatting The file script.js has been updated to adopt the new format provided by webpack, a tool for managing web resources. This has helped to enhance the structure of the code.
Better Interaction Handling for Menu Items The code that handles user interactions, such as clicking, with the hamburger menu and the sidebar in script.js has been updated for improved performance.
Standardisation across scripts The webportal-script.js file has been updated to mimic the changes implemented in script.js. This ensures consistency in the codebase across different scripts.
Improved Resource Loading The mix-manifest.json file has been modified to include unique cache busting IDs for our JavaScript and CSS files. This ensures that whenever these files are updated, the users always load the latest versions, improving their experience.
Minor Comment Addition An extra piece of documentation has been added in routes/web.php to aid in the redeployment process. Please note this doesn't impact functionalities.
