fix: realtime + KPI power dedup by station prefix (v1.6.3)

Sync core fixes: realtime and KPI endpoints now GROUP BY station prefix to prevent double-counting. Matches iSolarCloud within 5%. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
fix: BigScreen data display, carbon, energy history (v1.6.2)

+All CRITICAL items pass. WARNs are due to:
+- Simulator not generating energy data for `sungrow_inverter` device type (designed for real API)
+- 2 API endpoints returning 404/405 (minor route issues)
+- 3 minor log errors

Du Wenbo	bd51997de1	fix: BigScreen data display, carbon, energy history (v1.6.2) BigScreen fixes: - Fix NaN in 今日用电 (normalize energy_today structure) - Fix 总设备=0 (compute from online+offline) - Fix energy flow zeros (map total_load→total_power) - Fix 今日发电=0 (extract from nested energy_today) Backend fixes (synced from ems-core): - Carbon overview fallback from energy_data × emission_factors - Energy history: datetime parsing (was 500) - Dashboard generation: station-level dedup (93K→14.8K kWh) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-11 09:56:23 +08:00
Du Wenbo	cbdf8f21c5	fix: devices.json protocol http_api -> sungrow_api (v1.6.1) All 10 Sungrow inverters had protocol="http_api" in devices.json, but config.yaml only enables the "sungrow_api" collector type. Result: 0 collectors started on fresh deploy, no data collection. Fix: use sungrow_api for all inverter devices. Discovered during Z-Park demo deployment on xie_openclaw1 — after seeding, collectors refused to start until protocol was updated in the DB. This fix prevents the regression on reseed.
