Fix: Teams Page bottom padding adjustment

Description

This PR fixes the bottom padding padding for the Teams page.

Before	After

Testing

1. Go to the TeamCardList.tsx file
2. Replace line 15 with this:

// This basically just increases the team cards rendered
{[items, items, items].flat().map(({ key, ...item }) => (

3. Visit the Teams page: http://localhost:9091/planex/teams
4. Scroll to the very bottom of the page
5. Verify that the team cards don't hug the bottom part of the browser viewport
