// Default deterministic scheduling strategy using three ordered passes.
//
// Pass 1 — Critical/inflexible loads
// Reserve their power in every slot regardless of price or solar.
//
// Pass 2 — Storage loads (battery, DHW tank)
// For each slot: charge if (solarForecastW - baseConsumptionW) > solarSurplusThresholdW
// OR if electricityPrice < chargePriceThreshold.
// Respects SOC/temperature max via targetValue.
//
// Pass 3 — Shiftable loads (EV, washing machine)
// Sort slots by composite score (price ASC, solar DESC).
// Assign the load to the N best slots before its deadline.
// Each assigned slot gets a human-readable decisionReason.
