Prayer Times Next Prayer Indicator Incorrect After Isha

Two issues were identified with the prayer times page: (1) When the page transitioned to showing the following day's prayer schedule after Isha, the underlying time data used for next-prayer calculations was not updated, causing the wrong prayer to be highlighted. (2) Drupal's page cache was serving stale prayer time data for up to one hour, which could display incorrect times, the wrong Hijri date, and an inaccurate next prayer indicator. Both issues have been resolved. The prayer times page now always returns fresh data on each request.
