Stock Picking Auto Create Lot Sequence

This module is a bridge that makes two existing features work together: automatic lot creation on stock transfers and per-product lot sequences.

When Odoo automatically creates a lot or serial number for a stock move line, it normally uses a general sequence. With this module, if the product has its own lot sequence configured and the lot numbering policy is set to "per product", Odoo uses that product-specific sequence instead.

• It only changes behaviour when the product has a lot sequence defined; otherwise the standard behaviour is kept.
• It only applies when the lot sequence policy is "product"; other policies fall back to the standard behaviour.
• It affects stock.move.line records, which are the detailed lines of stock transfers where lots and serial numbers are assigned.

There are no new menus, screens, buttons or reports. The change is automatic and invisible in the user interface, except that the generated lot/serial numbers follow the product's own numbering rule. Users configure the product's lot sequence in the product form (provided by the related module) and enable automatic lot creation on the operation type; this module then links the two.
