The kids' Quest Log again renders each instance's overdue state from
the API snapshot's `overdue` flag, which the API computes in the stored
application timezone. The browser-local overdue check from task
fd1093b5 (`_isOverdue` against `_now`) is removed; `_now` only drives
the header clock and date.
The admin settings route (PATCH /api/v1/admin/settings), the only
settings writer, now holds the missed-sweep scheduler's settings_lock
across the write and calls settings_changed, so saving `timezone` or
`day_rollover_time` re-plans a sleeping scheduler (review finding
TZ-001). An app without a scheduler just writes.
Tests: the card shows the snapshot's overdue state whatever the
browser's zone or clock says; an admin PATCH of the zone or the
rollover re-plans a sleeping scheduler; one saved zone
(Asia/Kolkata) is read identically by the panel snapshot, the admin
snapshot and the scheduler delay.
