Julian Pawlowski feaf748cb6 feat(services): isolate price-fetch failures and add success flag to responses ... Add a track_degraded parameter to IntervalPool.get_intervals so service calls (track_degraded=False) never flip the coordinator's sensor-health flags or use the covers-current-interval cache fallback; authentication errors still propagate. All price-fetching services now go through async_fetch_service_intervals and return a structured response with a top-level success flag: success=false with reason="price_data_unavailable" on a real API outage, and success=true (possibly empty) otherwise. Impact: Action calls (get_price, find_cheapest_*, plan_charging) always return the expected shape, never impair sensors during a Tibber outage, and let automations distinguish an outage from "no data yet".		2026-05-30 14:46:23 +00:00
