Fetches GET /api/prices?start&end&zone (15-min slots, EUR/MWh) and stores the raw market price as feed_in_tariff_wh (EUR/Wh) — no import charges/VAT. Slots beyond the day-ahead horizon are left to the consumer's forward-fill (FeedInTariffImport behaviour). 5 unit tests + opt-in live smoke (EOS_DVHUB_ONLINE_LIVE=1, passing).
