ServicingPipeline: make a bunch of quality of life improvements (#18830)

We used to cherry-pick every commit that had even one card in "To Cherry
Pick", even if it was also referenced by a card in "Rejected" or even
"To Consider".

Now we will warn and skip those commits.

I took this opportunity to add a bit of an object model for servicing
cards as well as prettify the output.

That allowed us to add a list of cards that were ignored due to having
no commits, and display little icons for each type of card.

(cherry picked from commit 8e94983)
