Before this commit the `_search_get_detail` result contained callback functions to handle special behavior during fetching and rendering. After this commit a `website.searchable.mixin` is introduced that must be inherited by models that participate in website-based searches. Custom behavior previously achieved with callbacks is now achieved by overloading methods of this mixin. task-2379555 https://github.com/odoo/odoo/pull/65871 Part-of: odoo/odoo#65871
