Mobile pivot views now use the updated group-by selection menu, matching the experience available elsewhere in Odoo. Users can choose predefined groupings from the search setup or add a custom group, making mobile analysis more flexible and consistent.

The groupby selection in a pivot view is now done via a menu similar to
the "Group By" menu in control panel: the groupbys proposed when a user
click on a suitable header are those defined in the search arch
and a "Add custom group" menu is also available for more flexibility.
For more information and precision see odoo/odoo#61572.
Here we simply adapt the mobile PivotRenderer to the above mentionned
changes.

Delivery packaging is now handled separately from product packaging, aligning shipping carrier workflows with updated warehouse package handling. This supports smarter putaway rules and improves consistency across delivery barcode, Bpost, DHL, and Easypost operations.

This fixes an issue where opening the steps list from a bill of materials could fail because the wrong list view settings were carried over. It also restores the expected default product and picking type values when creating quality steps, reducing errors and manual corrections for manufacturing users.

On the BOM form view, when go to the steps (quality point) list view, we don't pass the old context anymore as there is unused data for the quality point view and, even worst, a `tree_view_ref` who will cause a traceback (as it will try to open the operation view for the quality point model).
