The secondary window label logic treated any window >= 24h as "Day",
but Codex plans can have a weekly (604800s / 168h) quota window.
The reset timer showed "resets 2d 4h" while the label said "Day",
which was confusing.
Now windows >= 168h are labeled "Week", >= 24h remain "Day", and
shorter windows show the hour count.
