Features:
- Enumerate active ROS nodes from /rosout activity

- Heartbeat timeout: 5 seconds without updates = dead
- Display node name, status, uptime, and last seen timestamp
- Color-coded status indicators (green=alive, gray=dead)
- Sortable table with node statistics
- Summary card showing alive/dead node counts
- Periodic status polling every 2 seconds

Integration:
- Added to MONITORING tab group as 'Nodes' tab
- Subscribes to /rosout (rcl_interfaces/Log) to detect active nodes
- Real-time updates with smooth transitions
