feat(strommix): history-driven panels (residual load, dunkelflaute, neg-price, flow balance)
Aggregator route /api/strommix now reads three RustyCMS history-mode collections in parallel — strommix_history_de, price_de_history, crossborder_history_de — and projects derived metrics on top of the raw upstream snapshots stored there: - todayHourly: per-slot Last + Wind+Solar for the residual-load chart - negPriceHoursYtd: count of YTD slots where DE-LU day-ahead < 0 - crossborderTodayGwh / netCrossborderGwhYtd / crossborderByCountryGwhYtd: GW × slot-hours integrated into a per-country GWh balance - lastDunkelflaute / worstDunkelflauten: contiguous runs where (wind+solar)/load drops below 10 % for at least 1 h, top 5 by duration All four are null-graceful — collections that the CMS hasn't backfilled yet leave the corresponding panel hidden instead of breaking the widget. Five new components in lib/components/blocks/strommix/: - ResidualLoadChart.svelte — SVG line chart, no chart-lib dep - CapacityFactorBars.svelte — live vs installed Wind/Wind-Off/Solar - DunkelflauteCounter.svelte — last phase card + top-5 list - NegPriceCounter.svelte — YTD hours + manual EinsMan compensation - FlowBalanceTodayYtd.svelte — today + YTD saldo with per-country breakdown Block schema additions (block-types.ts + strommix-default.json5 in cms_content): installed_*_gw / installed_as_of for the capacity-factor bars (BNetzA Marktstammdatenregister snapshot, manually maintained), and einsman_costs_ytd_eur_mio / einsman_costs_as_of for the NegPrice panel (BNetzA quarterly report figures, no API).
