Refactor: remove usage of RateCard by AI (drafts, choose, etc)

RateCard.java used by AI for draft picks and some card choose dialogs. It’s outdated and unsupported, also it requires to find and download third party ratings for each new set.

There are already exist a multiple score systems:
- commander brackets;
- edh power level;
- battlefield score (combat evaluator);

RateCard logic looks like a battlefield score but used additional info about deck’s colors (used in limited use cases). So such logic can be integrated to battlefield score on rework.
