feat(webui): live operations dashboard (Issue #412)

Comprehensive real-time telemetry dashboard consolidating:
- Battery state & power (10Hz): voltage, current, SOC
- Motor PWM control (10Hz): left/right duty cycle display
- IMU attitude gauges (10Hz): roll, pitch, yaw visualization
- LIDAR polar map (1Hz): 360° obstacle visualization
- Social state (1Hz): speech detection, face ID
- System health (1Hz): CPU/GPU temps, RAM/disk usage
- 2D odometry trail (10Hz): position history map

Responsive 3-column grid layout (1-3 cols based on viewport).
Dark theme with mobile optimization. Canvas-based visualizations.
Real-time ROS subscriptions via rosbridge. Auto-scaling meters.
Quaternion to Euler angle conversion. 500-point trail history.

ROS Topics (10Hz critical / 1Hz system):
- /saltybot/imu → sensor_msgs/Imu (attitude)
- /diagnostics → diagnostic_msgs/DiagnosticArray (power, temps)
- /saltybot/balance_state → std_msgs/String (motor commands)
- /scan → sensor_msgs/LaserScan (LIDAR)
- /odom → nav_msgs/Odometry (position trail)
- /social/speech/is_speaking → std_msgs/Bool (voice activity)
- /social/face/active → std_msgs/String (face ID)
