fix: Replace nullable Float composable params to avoid ART native crash

ComposerImpl.changed() boxes Float? and calls Float.equals() at the ART native level, triggering a known crash. Non-null Float params use the primitive overload with no boxing.

Introduces BATTERY_UNKNOWN sentinel, toBatteryFloat(), and toBatteryOrNull() extensions to eliminate Float? from all composable signatures and WidgetRenderState data classes.
