The dashboard html page in the newAccount folders should be refactored as a component

Note that React Components by default go into the pages folder.

From the Next.js docs (https://nextjs.org/docs/basic-features/pages):

In Next.js, a page is a React Component exported from a .js, .jsx, .ts, or .tsx file in the pages directory. Each page is associated with a route based on its file name.

The dashboard.html page in the accountData folder uses the calendar.js file and calendar.css to create a calendar--see here to see how that calendar was built: https://css-tricks.com/how-to-make-a-monthly-calendar-with-real-data/
