Lutz Finsterle	0b51ce5240	Add ambient temperature gate to heating period detection ... Adds heating_min_ambient_c (default 15°C) to season config. When outdoor temperature is at or above this threshold, SG-Ready is suppressed even if the calendar month is within the heating season. Prevents unnecessary heat pump boost activation on warm spring/autumn days. Logic: heating active = in_heating_month AND ambient < threshold Zero value (unset) disables the temperature gate (calendar-only, old behaviour). New test: TestHeatingPeriodAmbientSuppression covers warm-day suppression, cold-day pass-through, and summer month independence.
