{# Notifications floating side menu — client-side tab switching (switchNotifTab in notifications.html), same markup/behaviour as the Settings/Integrations/ Monitoring menu (menu rework, July 2026). Dynamic entries come from get_dynamic_tabs('notifications') for any thirdparty registered with settings_host="notifications" and a settings_tab outside the built-in list below (see registry.py's resolve_dynamic_tabs() / _KNOWN_TABS) — grouped under a "Modules" heading, same as integrations.html. #}
