Stock Reserve Sales MRP

This module extends the stock reservation wizard used from sales orders. When you reserve stock for an order line that is a kit (a product with a phantom bill of materials), the module explodes the kit into its components and creates separate stock reservations for each component, rather than trying to reserve the kit product.

• It looks up the phantom bill of materials for the product on each selected sales order line.
• If no kit bill of materials is found, the line is handled by the standard reservation process.
• For kit lines, it calculates the required quantity of each component based on the ordered quantity and the bill of materials quantities.
• It creates stock reservations for each component, linked to the original sales order line, with the same validity date, source and destination locations, owner, and note as the wizard.
• The reservations are then confirmed (reserved) automatically.

This affects the sale.stock.reserve wizard and the stock.reservation model. It ensures that reserving a kit actually reserves its components, which is useful for warehouse teams preparing kits for delivery. No new menus or screens are added; the change happens inside the existing reservation wizard.
