Existing checklists
Import / update a checklist from CSV
Columns: task_id, time_label, description, depends_on, input_type, photo_required
plus optional recurrence, due_time, times, min_value, max_value.
depends_on is semicolon-separated task_ids.
input_type is check, yesno, text, or number
(min_value/max_value flag out-of-range numbers).
recurrence is daily, weekly:mon;wed;fri, monthly:15,
or an nth weekday like monthly:2nd-tue / monthly:last-fri.
due_time (HH:MM) marks a task overdue after that time;
times (10:00;14:00) makes separate check-offs per time.
Columns you leave out keep whatever the Task List Editor has set.
Tasks keep their original created-date when re-imported (used for the NEW badge).
