feat: enhance globe visualization with traffic arcs

Adds real-time visualization of traffic flow between user locations and data centers on the 3D globe:

- Implements arc animations for traffic visualization
- Adjusts globe colors and atmosphere for better visibility
- Adds data center (colo) location mapping
- Centers initial view on user's current location
- Improves mobile responsiveness and layout
- Adds cleanup handling for globe resources

Performance and UX improvements:
- Optimizes globe rotation speed and controls
- Updates time picker layout with logical grouping
- Enhances responsive design for dashboard components
