Fix migration graph: restore missing 0006 file, add 0008 cleanup

0007_merge referenced 0006_item_category_unending which git had
renamed, causing NodeNotFoundError on clean DBs. Restores the file
so both 0006 leaves exist, then 0008 reverts the stale category
choices back to the correct set (no unending in category).
