[verified] review fixes: priority arbitration, wildcard config, dead code

- CheckReactions: collect all claims, pick highest priority (win>kong>pung>chi)
- Deal(): read wildcardCount from DSL config instead of hardcoded 4
- CheckTing(): propagate wildcardCount + require258Pair to CheckWin
- ThirteenOrphans: fix neededForPair formula (extra>0?0:1)
- Remove FanConfig.Get() dead code
- Fill empty 全不靠 test body
