Upgrade and refactor project

[steve1316]

Description

Project is being moved from a VPS to self hosting. Usage of Docker is now required to automate and to ease transitions across servers from now on and to redeploy whenever it is required.

• Move project from CRA to vite for build and dev server.
• Upgrade all frontend packages including react and @mui to their latest.
  • Consider if we should split up the project into /backend and /frontend folders. For docker-compose, perhaps?
• Upgrade all backend packages. Consider if we should replace nodemon with something better.
• Create Dockerfile to deploy the mail server for the website's password recovery.
• Perform a comprehensive code review. There is room for improvement and code consolidation.
• /about page needs to be created.
• Cull unused packages and leftover files from CRA.
• Update README.

Afterwards, we will need to rethink the data collection and use cases. There is room to do more analytics but that will require reconstructing how and what data will be collected from GA and GAA.
