Render the admin Schedule tab (ADMIN-SPEC §4): a month grid per child
showing home, away, override and today states, with cycle position
computed from the anchor date by floor division (never ISO week
parity), a presence pattern card, and the overrides list. Tapping a day
toggles that cycle week's weekday; anchor date and cycle length are
editable and Save pattern PUTs the schedule to the admin presence
route. The override editor (Add/delete) is left inert for 4ae0c879.
