* minor migration refactor * overwrite usdx claims with latest reward indexes * add missing usdx claims in migration * add script to calculate missing usdx rewards * generate missing rewards using preliminary data * add missing usdx rewards in migration * update missing rewards data to use correct genesis * test rewards were not decreased * add tests for missing reward calculations * clarify function names * test to assert total new rewards are as expected * remove unecessary todo item
