As a final task, we want to store some of the user's personal data into a simple file-based “database” on the server.

• Check the account-details.html template page for any TODOs there!
  • Ultimately, the form inputs should be pre-filled with the values stores inside the database.
• Implement the /account-details route handler to read / write to the database.txt file on the server;
  • You will have to support both GET and POST, so make sure to edit the decorator's arguments!
