Consumer #706 / Admin #360 — Week boundary moves Monday to Tuesday, cutover 2026-09-01

A week now runs Tuesday through the following Monday. Going forward only, no historical recompute. Consumer half is #706, admin half is #360. **Test (Tier 2):** the picker snapping to Tuesday rather than Monday is checkable now. Full behaviour only observable across the 1 September cutover. **Still open:** whether the changeover week runs short or long, and whoever publishes needs to know before scheduling a required set into it.
