Fluval Plant Pro 4.0: reconstructing BLE light control

The Fluval Plant Pro 4.0 project reconstructs the light's CBOR-over-BLE control protocol from the FluvalConnect Android app. An ESP32 ESPHome configuration sends commands through vendor service FFF0 and exposes power, five color channels, schedules and state updates to Home Assistant.
