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.
