fix(reconcile): close W10 QA H1 + Mediums

- H1 drag handle wraps GripVertical in a 44 × 44 px ::before pseudo-element matching the Switch primitive's pattern from v1.4.43 W5-H1; visible icon stays at 28 px (design)
- M1 dnd-kit sortable transition honours prefers-reduced-motion (design)
- M2 CHANGELOG voice slips ('marathon', 'touch-disjoint', 'Marc-voice strings throughout') replaced with neutral phrasing (code-reviewer + product-lead M-1)
- M2 OAuth handshake claim corrected — cookie name preserved but value shape changed; in-flight CSRF fails + retry needed (product-lead M-2)
- M3 operator notes call out the migration-must-run-first ordering with the partial-deploy failure mode (product-lead M-3)
