Fix rainbow pattern step range in lighting controller

- Change step calculation from beat_index % 2 to beat_index % 256
- Provides full 0-255 step range for rainbow pattern color cycling
- Fixes rainbow pattern that was limited to only 0 or 1 step values
- Alternating phase patterns still use % 2 for proper phase offset
