jensandClaude Sonnet 4.6 d02b7cbe72 Clean up after Smith predictor rewrite and drop unused/stale config
[brewpi] - drop trace vars for the dtheta_ist_* attributes removed
when temp_controller_smith.py dropped Kalman filtering
[Pot] - drop unused kn field (never read since the noise-injection
code that used it was dropped)
[GUI] - default WS connection to ws://localhost:8765
