This update modernizes parts of Odoo's Mail and Discuss experience using a newer interface framework. It improves how messaging areas behave while loading and includes fixes around message composition, attachments, notifications, and internal test support, helping make the mail experience smoother and more reliable.

The website editor's left panel now handles empty and default input values more consistently. This reduces confusing displays and helps ensure option visibility updates only after the underlying values are ready.

addendum to fdc4ef97c9d09ce07aa2e747041d973a3e607af5 We would not create foreign key constraints since dfaea03de57394a9a188f499da664c57dd9adc29 due to the inexact check. The check would favour the tables/views from the `information_schema` rather than those created by Odoo (in the `public` schema typically). https://github.com/odoo/odoo/pull/40930 made a slight change that seems to invert the order of the results and revealed the underlying problem.
