Update styles for card and schedule

Description

I'd like to think my code is usually pretty good, but I am sure this time it's not. I just feel like there was a bunch of different stuff going on here and it feels messy. I hate it here.

Removing cmd-f dependent styles

So for last year's cmd-f flavour for Portal we put a bunch of conditional styling that read something like

p => p.theme.name === 'cmdf' ? <cmd-f styles> : <regular styles>

We did it this way before because there were neat images and stuff, but this year we don't have that. I removed the instances of this that I could find because it was really messing with our "regular" cmd-f theme that we have this year.

Updating card styles (I sure hope so)

Basically I'm putting blanket styling on how cards should look in Portal. I thought it was strange that cards depended on secondaryBackground. Thus I've introduced card and cardText. All Cards will now have a bg of card and their text will be color cardText.

Schedule

We're going with a bit of a different schedule design this year. The problem I was running into was that the styles for the schedule page was being overwritten by the styles from CardLike in Common.js. My solution is to copy CardLike into Schedule.js (removing the styles that I don't want).

I left a TODO so that we can come back to this PR and see that I was very dumb and we should go back to how things were before. If anybody has a better solution here PLEASE let me know, but I feel like I'm in too deep.
