feat(missions): emit progress events on story/finish and practice/finish

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.
