1. Instead of having two selectors, we use the `.list-group-item` class and have coverage for list items and anchors.
2. Rather than override all border values, we only override what we set with `border-top`.
- Instead of negative left/right margins, we selectively apply margins to the cards as needed. This way the first and last child never receive a left and right margin (respectively), so we don't need to negative indent those at the .card-deck level.
- Drops the margin-bottom override on the .card because there's no more default margin there.
- Drop the margin-bottom from the .card-deck to match our lack of margins on the card.

Related #18726
When you use a `<hN>` as `.card-header` there is `margin-bottom: .5rem` added. The changes set the margin-bottom to 0
* Removed space
* Add .img-fluid to card images in columns to ensure proper resizing
* change that variable from regular value to variable
* use calc to figure out a tighter border for card images
Here we're doing some margin swapping, so it looks a little funky. All this does is match the margin implementation and rendering across our table and flex versions of card decks.
- Remove the box-shadow and switch back to border to match .card basics
- Update the header nav margin override--since we restored the border, we need that default negative margin at the bottom
- Drops the experiment I had going for `box-shadow`-powered borders
- Reinstates regular `border` using existing variables
Fixes #19097 and #19143. Nullifies #19828.
