Add Deck Validity Status when Constructing Deck about 0xfable HOT 1 OPEN

To clarify, the check made before the game is already implemented here and run currently! It's implemented here

So that only leaves the check in the frontend, we can do that by calling the implementation and checking if it throws an error (and down the line use the specific error to print a message that points out the specific problem).

I'm not sure what constructor you're referring to in the title?

Regarding the deck limitation, I wouldn't worry about it too much, 256 is plenty, we'll just need to add a warning when that limit is reached + hide the "new deck" button when that occurs.
