Remove ALL mocked data - production-ready admin console

BREAKING CHANGE: Admin console now requires actual running nodes

Removed all mocked/hardcoded data:
✓ Metrics now fetch from real Prometheus endpoints on nodes
✓ Config persists to disk (.bitcell/admin/config.json)
✓ Setup state persists to disk (.bitcell/admin/setup.json)
✓ Deployment status shows real registered nodes
✓ No more placeholder/fake data anywhere

New Components:
- MetricsClient: Fetches and aggregates metrics from node Prometheus endpoints
- SetupManager: Persists setup state with node endpoints configuration
- Setup API: 5 endpoints for configuring the admin console
  - GET /api/setup/status - Get current setup state
  - POST /api/setup/node - Register a node endpoint
  - POST /api/setup/config-path - Set config file path
  - POST /api/setup/data-dir - Set data directory
  - POST /api/setup/complete - Mark setup as initialized

Production-Ready Features:
- File-based config with auto-save on updates
- Real-time metrics aggregation from multiple nodes
- Graceful error handling when nodes are offline
- Clear error messages guide users to complete setup
- Deployment status reflects actual registered nodes

Configuration Flow:
1. Start admin console
2. Use setup API to register node endpoints:
   POST /api/setup/node with {id, node_type, metrics_endpoint, rpc_endpoint}
3. Mark setup complete: POST /api/setup/complete
4. Admin console fetches live metrics from registered nodes

All metrics endpoints now return:
- 503 Service Unavailable if no nodes configured
- Real aggregated data from all responsive nodes
- Errors array listing any unreachable nodes

This is a true production-ready administrative tool.
