Refactor dashboard overview: remove active alerts and lagging nodes from summary, update tests and components accordingly

- Removed active alerts and lagging nodes from DashboardSummary and related types.
- Updated DashboardOverview component to reflect changes in data structure.
- Adjusted tests to align with the new dashboard overview structure, ensuring no active alerts are displayed.
- Simplified the dashboard metrics and risk signals, focusing on essential health and capacity metrics.
- Enhanced the WorldStage component to present updated traffic and capacity information.
- Removed unused alert-related functions and components to streamline the codebase.
