The /eskaera/load-draft endpoint was returning previous-cycle drafts when
group_order.cutoff_date was still in the future but group_order.pickup_date
had not yet been recomputed (its compute only depends on pickup_day and
start_date). Both the stale group_order.pickup_date and the old draft's
pickup_date held the same past value, so the exact-pickup-date filter in
_find_recent_draft_order matched the stale draft and the cart was
repopulated with old products immediately after being cleared.
Replace the pickup_date exact-match + current-week fallback with a single
cutoff-anchored window: create_date in [cutoff_date - 6 days, cutoff_date].
Drafts created outside that window belong to a previous cycle and must
not be reused. The change applies to all four callers (load-draft,
clear-cart, save-order, confirm) so the merge/confirm paths also stop
attaching to stale drafts.
Covered by a new regression test that mirrors the production setup
(matching pickup_date, draft create_date backdated 10 days).
