* Small changes to some card-related debug verbs (#72361)
## About The Pull Request
Test Card Distribution debug verb has been altered slightly to prevent
runtimes. Backing out of any one of the menus would send null as an
argument, and cause a runtime.
The Validate Cards verb now returns a message if no errors are found. I
kept mistakenly clicking this verb thinking it was the Cardpack
Distribution one, and would get confused whenever nothing happened. Now
it returns a message!
Also converts some of the stuff I touch into snake case because pretty
code is nice.
## Why It's Good For The Game
Closes#66987. Feedback for the random debug buttons I accidentally
click is good.
## Changelog
