Task: [3636092](https://www.odoo.com/odoo/project/2328/tasks/3636092)

The manufacturing planning screen now orders related items more reliably, including complex products with several bill of materials levels. Opening planning from a bill of materials now shows all related child items, helping teams get a fuller view of demand and dependencies without extra navigation.

This PR contains the following commits:

- see all the children MPS when opening from a specific bom and not just the first level
