Plan:
- Update `index.php` to use a dynamic page title (`__($page)`) instead of the hardcoded "Accounting".
- Add "Copy Outlet Data" to `includes/lang.php` (both English and Arabic) to ensure the title displays correctly without hyphens.

Changed:
- `index.php`: Changed `<title>` tag to use `__($page)`.
- `includes/lang.php`: Added `'copy_outlet_data' => 'Copy Outlet Data'` (and Arabic equivalent).

Notes:
- This change also fixes a bug where *every* page was previously titled "Accounting - Admin Panel". Now all pages will show their correct titles (e.g., "Dashboard", "Sales", "POS").

Next:
- Refresh the "Copy/Sync Outlet Data" page to see the new title "Copy Outlet Data - Admin Panel".
- Reminder: click Save in the editor to sync changes.
