…t duplicates - ParseDeliveryDate() now uses DateTime.SpecifyKind+ParseExact for date-only strings so DAILY/MONTHLY delivery dates are always stored as UTC midnight regardless of server timezone (fixes duplicate rows when running on UTC+2 vs UTC Docker) - Remove redundant .ToUniversalTime() calls in ElectricityPriceFetchService - Migration: deduplicate and normalize existing DAILY/MONTHLY rows (DATE_TRUNC) - Migration: re-run normalization with +12h rounding for Norway-local UTC offsets - Migration: delete remaining bad-date MONTHLY rows (day != 1) and all DAILY rows so the service can repopulate them cleanly on next startup

Fix duplicate electricity price bars in weekly/monthly/yearly charts.
Root cause: DateTime.Parse on date-only strings from Nord Pool returned Kind=Unspecified. .ToUniversalTime() assumed server local time, so Docker (UTC) and Windows Norway (UTC+2) stored different UTC keys for the same date, bypassing the unique index and creating duplicate rows.
