C-01: Add 30-day lower bound on overdue todo/reminder queries to
prevent fetching entire history.
C-02: Remove dead include_past query param — past-event filtering
is handled client-side.
W-01: Add onError toast handlers to all three inline mutations.
W-02: Snooze dropdown opens upward (bottom-full) to avoid clipping
inside the ScrollArea overflow container.
S-06: Clamp getMinutesUntilTomorrowMorning() to max 1440 to stay
within ReminderSnooze schema bounds.
