feat: add undo functionality with ctrl+z

[kamui-fin]

Resolves #673

Essentially creates an undo stack reducer with callbacks that perform the opposite operation of any user action (handle* functions). So far seems to be working, however, I will perform some more manual testing before merging.

Overall looks okay aside from a few bugs here and there. As discussed on Discord, we shouldn't undo for filters and selections though.

Seems like there's a build error in a weird spot. Could you sync with develop? #679 changes the implementation of handleDeleteAllSelectedCourses.

It seems like deleting a course from a semester can't be undone atm. I think we should have that.

Also, do you think you could add an undo for mass deletion of selected courses? Overall looks good though! Can't wait to see this in prod
