feat: Add VESC balance PID controller with tilt safety (Issue #407)

Browse Source 
- ROS2 node for balance mode PID parameter management via pyvesc UART
- Tilt safety kill switch: ±45° pitch > 500ms triggers motor cutoff
- Startup ramp: gradual acceleration from 0 to full output over configurable duration
- IMU integration: subscribe to /imu/data for pitch/roll angle computation
- State publishing: /saltybot/balance_state with tilt angles, PID values, motor telemetry
- Data logging: /saltybot/balance_log publishes CSV-formatted IMU + motor data
- Configurable parameters: PID gains, tilt thresholds, ramp duration, control frequency
- Test suite: quaternion to Euler conversion, tilt safety checks, startup ramp
