Dynamic Subject Loading from pesuacademy.com

Create a backend service that logs into pesuacademy.com with a user's credentials, scrapes their course data for the current semester, and then sends it to the PESto-do app. The app would then dynamically display the checklists for the subjects the user is enrolled in.

- Create API endpoints to send the scraped subject data to the frontend.
- Modify the frontend to fetch and display the subjects dynamically for the logged-in user.
- Implement a secure authentication system to manage user sessions.
