Brand asset fix
The integration's brand/ PNGs (icon, logo, @2x variants) were RGBA on disk but every pixel was fully opaque — the background rendered as white on HA / HACS cards instead of blending in like other integrations' icons.
Flood-filled the white background from the image borders (interior white of the config-panel graphic is intact), so the icons now composite correctly on any card color and theme.
No code changes. Version bump so HACS surfaces this as an update.
