Stock Product Catalog

This module brings the product catalog feature to stock transfers (pickings). When you are on a stock transfer, you can open a catalog view to browse products and add them as move lines. The catalog is available from the transfer form via a 'Catalog' button that appears when the transfer is not in draft state.

On the operation types (like Receipts, Delivery Orders), a new menu item 'Planned transfer from catalog' is added to the kanban view. Clicking it creates a new draft transfer and opens the catalog directly, so you can start adding products right away.

The catalog only shows storable and consumable products. When you add a product, a stock move is created with the quantity you specify. If you change the quantity, the move is updated; if you set it to zero, the move is removed (if the transfer is still draft) or set to zero quantity. The catalog also respects the transfer's state: if the transfer is cancelled or done, the catalog becomes read-only.

The module works with the existing product catalog mixin and extends the stock picking, stock move, and operation type models. It also patches the catalog's user interface to show 'Back to picking' instead of the default button and hides prices for stock transfers.
