Add BACKBEAT Clock component to WHOOSH dashboard

Features implemented:
- Real-time BACKBEAT pulse monitoring with current beat display
- ECG-like trace visualization with canvas-based rendering
- Downbeat detection and highlighting (every 4th beat)
- Phase monitoring (normal, degraded, recovery)
- Average beat interval tracking (2000ms intervals)
- Auto-refreshing data every second for real-time updates

API Integration:
- Added /api/v1/backbeat/status endpoint
- Returns simulated BACKBEAT data based on CHORUS log patterns
- JSON response includes beat numbers, phases, timing data

UI Components:
- BACKBEAT Clock card in dashboard overview
- Live pulse trace with 10-second rolling window
- Color-coded metrics display
- Grid background for ECG-style visualization
- Downbeat markers in red for emphasis

This provides visual feedback on the CHORUS system's distributed
coordination timing and autonomous AI team synchronization status.
