Stock Restrict Lot Domain

This module extends the lot restriction feature by adding a company-level setting that controls which products are allowed to have their lot restriction changed.

In the Inventory settings, a new field called "Enforce lot restrictions" lets you enter a product domain (for example, a category or a specific product). If the domain is empty, lot restrictions cannot be changed for any product.

On transfer forms (stock.picking), the lot restriction field is shown in the operations list and in the detailed move form, but only for users in the lot/serial number group. Whether that field can be edited depends on the product: if the product matches the domain, the field stays editable; if not, it becomes read-only.

When you do change the lot restriction on a move, the change is automatically copied to all downstream moves (the next steps in the chain), and the move is re-assigned. This propagation only goes forward, not backward.

The module touches the company settings, the configuration settings screen, and stock moves. It relies on the stock_restrict_lot module for the underlying restriction field.
