Moved global stats logic from LayoutHelper to Domain model and updated views/controllers to use the new stats structure. Replaced direct $_SESSION['user_id'] access with Core\Auth::id() for consistency. Cleaned up redundant code and improved isolation mode handling for statistics.
Updated LayoutHelper::getGlobalStats to accept a user ID and apply user isolation mode when querying domain statistics. DashboardController and base layout now pass the user ID to ensure stats are scoped per user when isolation is enabled.
Improves bulk actions in the domains view by ensuring unique domain IDs are counted and selected, preventing double-counting from desktop and mobile checkboxes. Adds CSRF token to bulk actions forms for security. Moves timezone initialization to public/index.php to ensure it is set before any date operations, and updates base layout to reflect this change.
