This update ensures that references to the fragment query string functionality are accurate as it's being reorganized within Odoo. This change is part of a larger effort to improve the internal structure of the code and maintain consistency across modules. It ensures the social media integrations continue to function correctly.

The aim of this commit is to keep referencing fragment_to_query_string correctly as it is moved into `http.py`.
