Sale Order Blanket Order Stock Prebook Release

This module links blanket orders with the stock release process. When a blanket order is confirmed, the system automatically sets a 'Move Date Priority' based on the blanket order's validity start date. This priority is then used when releasing stock, so that orders are processed in the right sequence.

• For blanket orders, the commitment date and validity start date are kept in sync: changing one updates the other.
• When a blanket order's validity start date changes, the system recalculates the move date priority and updates the priority on all related outgoing stock moves that are not yet done or cancelled.
• When confirming a blanket order, the move date priority is set to the validity start date plus a small offset based on how many other blanket orders share the same start date, ensuring a unique order.
• For blanket orders with the 'at confirm' reservation strategy, the move date priority is passed to the procurement values, so that stock moves are created with the correct priority.
• The module also includes a post-installation step that computes the move date priority for all existing confirmed blanket orders and updates their stock moves.

This module works together with sale.order and sale.order.line and affects stock moves and their release priority.
