Fix: Scene clear no longer restores black (#18)
Two fixes for the remaining reports where selecting "None" in the scene selector caused the light to show rgb_color: (0, 0, 0):
-
API poll color preservation — Govee API returns
colorRgb=0as a sentinel when color is not the active mode. This no longer overwrites a valid existing color in HA state. -
Scene clear fallback prefers RGB white — When no previous color is saved, the fallback now sends white (
255, 255, 255) instead of a color_temp midpoint. The API reflects RGB values more reliably, preventing revert to black on the next poll.
