ErpGo Product-Warehouse Fix

The ErpGo script is freshly installed and untouched—no custom code has been added. When I create a new quotation the form asks for both Product and Warehouse, yet the interface never lets me link the two; the dropdown or selector for assigning a product to a specific warehouse simply isn’t there and no error message appears.

I need someone comfortable with Laravel and Tailwind who can trace why the product-warehouse selector is missing and restore the expected behaviour. Once you’re done I should be able to pick a product, choose its warehouse, save the quotation, and see the correct stock deduction reflected in the system.

Deliverable
• A clean code fix (pull request or patch) that reinstates the product-warehouse assignment in the quotation workflow and works across all standard browsers without breaking existing ErpGo features.
