feat(notifications): reminders for todos with upcoming due dates

Todos already support a due_date field but nothing notifies the user when a deadline is approaching — you'd only remember if you happened to look at the Lists tab. This wires a reminder into the existing notification pipeline so due-date todos behave like trip-start reminders. Details: - New `todo_due` event type alongside trip_reminder; all four channels (in-app, email, webhook, ntfy) supported and toggleable per user in Settings > Notifications. - New daily scheduler task (9 AM local TZ) queries unchecked todos whose due_date is within the next 3 days. Each todo gets at most one reminder per 24 hours, tracked via a new todo_items.reminded_at column (migration 116). - If the todo has an assigned user, only that user is reminded; if not, every member of the trip gets the notification. - Strings added in all 15 UI languages and for all notification carriers. - Gated by app_settings.notify_todo_due (default on) so admins can disable it globally.
