fix: write the five-field Approval block on version reset

[hkwuks]

Summary

Make hooks/version's Approval reset emit the same five-field block
hooks/task promote writes, so the plan gate and the version reset agree
on shape. A plan that followed the old four-field skill snippet (no
- Status:) previously made version refuse; it now writes the full
block instead. Skill's human record snippet gains - Status: approved.
Smoke locks the five-line order and covers the missing-Status fixture.
