MRP Auto Create Lot

When a user records production on a manufacturing work order, this module checks whether the finished product is set to create lots automatically. If it is and no final lot has been chosen yet, Odoo creates a new lot for that product and assigns it as the work order's final lot before the production is recorded.

This means shop-floor users do not have to manually enter or select a lot number when finishing a work order for products flagged for automatic lot creation. The lot is generated at the moment production is recorded, so the finished goods are traced without extra typing.

The module extends the manufacturing work order behaviour (mrp.workorder) and relies on the product setting that enables automatic lot creation, which comes from the stock picking auto-create lot functionality. It does not add new menus or screens; the change happens silently inside the existing "Record Production" action on a work order.

Business rules added: - A lot is created only if the product's auto-create lot option is enabled. - A lot is created only if the work order does not already have a final lot. - The newly created lot is set as the work order's final lot before the standard production recording continues.
