Add Past Enrollment Popup

[Douglas-Hong]

Summary

• Now that the enrollment history endpoint is implemented, we can bring back and improve the Past Enrollment popup.
• Currently, the popup just displays the enrollment history of the most recent lecture section offered.

Demo:

TODO

• [X] Make a request to PeterPortal to get the enrollment history, and parse the response
• [X] Create the popup and display an enrollment history graph
• [x] Cache responses
• [x] Add ZotTracker link

Test Plan

• Verify this works for classes in the most recent quarter (e.g. CS 132).
• Verify this works for classes that haven't been offered very recently (e.g. CS 122D from Spring 2023).
• Verify this works for classes that have never been offered before (force queryEnrollmentHistory to return null).
• Make sure it looks good on dark and light mode, as well as mobile.

Issues

Closes #341 Closes #182

Future Followup

• We should allow the user to see the enrollment history of any lecture that was previously offered: #830
