feat: Add API logging

Add logging to the API to keep track of specific requests and headers. Also added CORS middleware to handle OPTIONS requests.

- Updated the 'fetchData' function to also fetch 'totals' and 'userStats' data

- Updated the 'onMount' function to initialize the bar and line charts using the canvas references and data
