This update removes an unsafe data storage format from several Odoo areas and replaces it with safer alternatives. It also reorganizes how user defaults and action links are stored, improving security and maintainability while affecting configuration behavior across multiple business apps.

The Python module `pickle` is a security weakness. Remove its usage in Odoo modules `anonymization`. `pos_cache` and model `ir.values`. The latter has been split into a model `ir.default` for user-defined defaults and fields `binding_model_id` and `binding_type` for action bindings.

This update improves invoice reports by showing total amounts alongside tax group names and simplifying the tax section. It also adds or updates tax group setup for multiple country localizations, helping businesses present clearer tax information on invoices consistently across markets.

This update replaces older internal mechanisms for default values and action links with newer Odoo foundations. It helps keep many business apps consistent and easier to maintain, with little expected change to day-to-day workflows.
