Implement lazy load and separate routes

As the App.tsx is too long it will keep growing and will be hard to maintain also all routes with each page are not lazily loaded which will increase the size of the entry file.

To group and separate routes based on each main page, in react-router v6 we need to use the route with the main path and end with a wildcard to define as a root page. Example: /monitors which contains sub-routes like /monitors/:id, we can define the PageRoute in App.tsx as /monitors/* and only :id in the sub-route component. It might sounds
complicated but once we get used to it, it'll be easier and faster.

Here's the result before and after implementing lazy loading:
