Implement proactive forecast-driven car charging strategy
- Replace reactive export-threshold wallbox activation with proactive
logic: WallboxA/B activate when forecast ≥ mid AND PV ≥ threshold
AND SOC ≥ 35%, without requiring grid export surplus
- Add WallboxB no-car detection via grid-delta probe (no PM available):
after probe window, if grid shift < GridDeltaThreshW → no car, retry
after configured timeout
- Add EOD soft stop: after 16:00, stop proactive car charging if
remaining PV estimate can't cover battery deficit to 90% by sunset
- WW boost no longer requires export threshold; dynamic setpoint uses
tank top temp + hysteresis + boost delta, capped at 60°C
- Proactive wallboxes bypass import-hysteresis shutdown; SOC emergency
brake uses SOCFloor (5%) instead of standard AllConsumers gate
- Add WWTopTempC to SystemState (ww_top_temp metric from DHW cylinder)
- Add BatteryConfig (capacity_kwh), CarChargingConfig to config
- Add WWMaxSetpointC, WWHysteresisC to StrategicConfig
- Update Decide() signature: forecastKWh + sunsetTime parameters
- Update all tests; add proactive charging test cases
