Legacy bulk upload not migrated

The old CSV importer (bulk_upload.php) that pushed raw rows into product_details, price_details, stock_details, and catogary_list is not available in the Laravel app. This prevents unsafe direct inserts that bypass validation and stock movement logic.

• Use the POS product form to add or edit items, prices, and stock with validation.
• If you need a CSV import, please coordinate with the tech team for a guided migration script.
