PracticeController.Finish now uses MissionEventKeys.Practice.WinAll — the
counter keys emitted match the catalog's named form (practice_win:elite:arisa
etc.), closing the numeric-vs-named mismatch that had all practice-elite
achievements silently at zero. Also removes the "bridging is a follow-up" TODO.
StoryController.Finish uses MissionEventKeys.Story.ChapterFinishAll for the
same shape. ItemPurchaseController.CounterKey routes through
MissionEventKeys.ItemPurchase so the "item_purchase:" prefix has one owner.

Story emits story_chapter_finish:<main|limited|event>:<story_id>.
Practice emits practice_win:<difficulty>:<enemy_class_id> on win only.
Practice catalog rows use opponent NAMES (e.g. practice_win:elite:arisa)
not numeric class_ids, so captured catalog rows won't match yet. The
infrastructure is in place; bridging numeric→name is a follow-up.
