This pull request introduces several enhancements to the activity management system, including the addition of new activities, validation for duplicate sign-ups, and UI improvements to display participant details. Below are the key changes grouped by theme:

Backend Enhancements:

• Added six new activities (Soccer Team, Basketball Team, Art Club, Drama Club, Math Club, and Debate Team) to the activities dictionary, each with a description, schedule, maximum participants, and initial participants. (src/app.py, src/app.pyR41-R76)
• Implemented a validation step in the signup_for_activity function to prevent duplicate sign-ups by checking if the user is already in the participants list. If so, an HTTPException with a 400 status code is raised. (src/app.py, src/app.pyR101-R104)

Frontend Enhancements:

• Updated the activity card in the frontend to display a list of participants for each activity. This includes rendering participant emails in an unordered list under a new Participants section. (src/static/app.js, src/static/app.jsR28-R33)

Styling Improvements:

• Added CSS styles for the new Participants section, including a styled container with a light blue background, rounded borders, and customized text colors for better readability. (src/static/styles.css, src/static/styles.cssR145-R169)

Consider normalizing email addresses (e.g., converting them to lowercase) before checking for duplicates to ensure consistency.
