Refactor monitoring grid to use GridViewMonitoring

Replaces all references to GridView5 with GridViewMonitoring for clarity and maintainability. Updates layout save/restore logic to use the new view, adds a helper for loading layouts, and improves default layout restoration. Cleans up designer and resource files, removing obsolete entries and ensuring correct initialization.
