Schedules Page Improvements

[Xavilien]

Description

Made some improvements to the schedules page that I found helpful when trying to build a schedule:

• Show schedules for each course (very helpful to see who is teaching it next semester without clicking into the course)
• Hide the course list summary which takes up a lot of screen real estate
• Add total number of units (so that I don't have to do math)

Closes #140

Type of change

• New feature (non-breaking change which adds functionality)

How Has This Been Tested?

• Tried building schedules in the schedules page

Test Configuration:

• Node.js version: 18.18.0
• Desktop/Mobile: MacBook Air M2
• OS: Mac Sonoma
• Browser: Safari
