Sale Stock On Hand Popup

This module adds a small arrow button next to the quantity widget on sale order lines, both in the order lines list and in the line detail form. Clicking it opens a popup showing the stock quants of that product, so salespeople can see where the stock actually is before confirming a sale.

The popup lists, for each stock quant: the location, the lot/serial number (if lot tracking is enabled), the package (if package tracking is enabled), the owner (if owner tracking is enabled), the available quantity, the quantity, the unit of measure and the company (if multi-company is enabled). A Close button ends the popup.

By default only internal locations are shown. In Inventory settings, under a new "Sale Stock on Hand" section, you can tick "Display also transit location lines in sale line stock popup" to include transit locations as well. This option is controlled by a hidden group, so it can also be granted per user.

The module touches product.product (to build the popup action), sale.order (to add the button on order lines), res.config.settings (for the setting) and introduces the product.quant.wizard model used by the popup. It depends on sale_stock and stock_available.
