chore(work): finish 01-wire-use-case-helper

Catches up the story's checkbox + frontmatter status to reflect that
the slice shipped in commit 1bbe866. The V1 orchestrator landed the
implementer's slice commit on main but had no state-mutation step,
so the bullet stayed unticked and `pnpm work next` would have
redundantly re-dispatched the implementer for a no-op slice.

Bookkeeping-only — no code changes.
