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 DashboardController, DomainController, and NotificationGroupController to conditionally fetch user-specific or global data based on the 'user_isolation_mode' setting. This ensures that data visibility aligns with the configured isolation mode, improving multi-user support and data segregation.
Refactored controllers and models to always filter data by user ID, removing admin bypass logic. This ensures all statistics, groups, domains, and tags are user-specific regardless of isolation mode, improving data isolation and security.
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.
Introduces user isolation mode, allowing domains, groups, and tags to be visible only to their owners when enabled. Adds user_id fields to domains and notification_groups, updates models and controllers for isolation-aware queries, and provides admin UI and endpoints for transferring domains and groups between users (single and bulk). Includes migration, settings UI, and routes for toggling isolation mode and handling data migration.
Extended the domain filtering logic and UI to allow filtering by 'available' and 'error' statuses. Updated the Domain model to handle these new filters and adjusted the dashboard to include global stats, including inactive domains.
Introduces error log tracking with new ErrorLog model, controller, views, and migration. Adds admin UI for viewing, resolving, and deleting errors. Implements bulk actions for users and notification groups, refactors domain filtering/pagination, and centralizes admin access checks using Auth::requireAdmin().
