fix: PGXL status-bar chip and Station Control widget read OPERATE from the Flex when it reports the amp (the direct GSCP status doesn't carry operate state) — toggle then goes through FlexAmpOperate like the Flex panel; direct TCP link stays as fallback; log distinct raw PGXL status payloads to map unknown fields
