Restrictions filter

[KevinWu098]

Summary

Currently implemented as a filter in CourseRenderPane.tsx, but will soon ^tm be in PeterPortal 😋

Implemented a dropdown checkbox menu into Legacy / Manual search to allow users to remove courses with certain Restriction codes from appearing in search results.

Test Plan

Make it work :')

Issues

Closes #595

Additional Notes

I mean gosh darn is the code scuffed, but I'll probably rewrite it when the Peterportal stuff happens

I've taken a one-minute glance, so this isn't comprehensive. Just some things to keep in mind:

1. The dropdown is no readable with light mode
2. Idiomatically, the filtering should be done on the API side, I think. @ap0nia?

Thanks for the feedback 💖

1. The dropdown is no readable with light mode

100% the styling is giga scuffed and I'll clean it up once the rest is done

2. Idiomatically, the filtering should be done on the API side, I think. @ap0nia?

100% this as well. Spoke with Eric about it and that's definitely the way I want to go about it.

In the meanwhile, I've been tinkering on a way to just filter the Websoc response while we're in the in-between
