SESSIONS PAGE TIME DISPLAY FIX

1) Add this near the top of backoffice/sessions.php, after config/header includes:

require_once __DIR__ . '/includes/session-time-format-helpers.php';

2) Replace the Clock In cell output with:

<td><?php echo wcps_format_clock_in_cell($row); ?></td>

3) Replace the Clock Out cell output with:

<td><?php echo wcps_format_clock_out_cell($row); ?></td>

4) If your current code prints raw values like:
<?php echo htmlspecialchars($row['clock_in_time'] ?? ''); ?>
or
<?php echo htmlspecialchars($row['clock_out_time'] ?? ''); ?>

replace those raw outputs with the helper calls above.

Expected result:
- Clock In shows:
  2026-04-08
  06:06
- Clock Out shows:
  2026-04-08
  16:37
- Midnight auto-close still shows:
  24h00
