PACKAGE LIVE1c - REAL SIDEBAR MENU INTEGRATION

Problem:
- The visible left sidebar is generated by /backoffice/header.php, not /backoffice/dashboard.php.
- LIVE1b added dashboard body cards, but did not change the sidebar menu shown across all backoffice pages.

Fix:
- This package patches /backoffice/header.php.
- It adds the new working lunch/payroll links into the real left sidebar menu.

Menu order after patch:
- Dashboard
- Staff
- Add Staff
- Worksites
- Add Worksite
- Assignments
- Sessions
- Working Lunch Report
- Date Range Report
- Monthly Summary
- Staff Hours
- Payroll / Lunch Rules
- Payroll Working Lunch Export
- Sage Payroll Export
- Exceptions
- Logout

Important:
- The old menu link /backoffice/payroll-export.php is replaced with /backoffice/sage-payroll-export.php.
- This matches the WL5 Sage export file created earlier.
- If you still need the legacy payroll-export.php page, keep a manual bookmark to it.

Extract inside:
- /home/uent/public_html

It places:
- /home/uent/public_html/backoffice/header.php
- /home/uent/public_html/README-LIVE1c.txt

After extraction:
Open:
- https://uent.co.za/backoffice/dashboard.php

Expected:
- The left sidebar now shows Working Lunch Report, Payroll / Lunch Rules, Payroll Working Lunch Export, and Sage Payroll Export.
