dashboard improvements (#896)

- Feature: Added Workspaces dashboard page with HTTP request stats and per-workspace metrics
- Feature: Added Build Storage dashboard page with service-specific HTTP request stats
- Improvement: Front page now shows Hub and Object Store activity tiles; HTTP panel is fixed above the tiles grid
- Improvement: HTTP stats tiles now include 5m/15m rates and p999/max latency across all service pages
