Fix redistribution cap bug - subtract instead of add overdistribution values

- Fixed bug in games_thread.py where overdistribution values were incorrectly
  added to the redistribution balance instead of subtracted. Now when we
  overdistribute (negative adjustment), we properly DECREASE the balance.
- Added Migration_068 to reset redistribution balance to 0 after the bug fix.
- Version bumped from 10.0.22 to 10.0.23
