PACKAGE LIVE1d - KEEP SIDEBAR ON NEW PAGES

Problem:
- The new pages from WL2/WL3/WL4/WL5 were standalone pages.
- When opened, they did not use /backoffice/header.php and /backoffice/footer.php.
- Result: the left sidebar disappeared.

Fix:
- Rebuilds the new pages so they use the normal backoffice shell:
  require_once __DIR__ . '/header.php';
  require_once __DIR__ . '/footer.php';
- Keeps the real sidebar visible on:
  /backoffice/payroll-lunch-rules.php
  /backoffice/working-lunch-report.php
  /backoffice/payroll-working-lunch-export.php
  /backoffice/sage-payroll-export.php
- Also includes the patched header.php with the new menu links.

Extract inside:
- /home/uent/public_html

Files placed:
- /backoffice/header.php
- /backoffice/payroll-lunch-rules.php
- /backoffice/working-lunch-report.php
- /backoffice/payroll-working-lunch-export.php
- /backoffice/sage-payroll-export.php
- /README-LIVE1d.txt

After extraction:
Open:
- https://uent.co.za/backoffice/payroll-lunch-rules.php

Expected:
- Sidebar stays visible.
- Page title appears in the normal backoffice topbar.
- Payroll / Lunch Rules content appears inside the backoffice layout.
