menubar: relative reset countdown — "resets 42m / 7h / 3d"

Replaces the two-format split (H:MM countdown for 5h, calendar date for
weekly) with one coarse single-unit formatter for both rows. Ceil at
every tier so the label never understates the wait. No date library —
it's one subtraction and two divisions.
