List all RGBW light components on the specified device with their current status.
RGBW components control color-capable lights with an additional white channel.
Each component has an ID, optional name, state (ON/OFF), RGB color values,
white channel value, brightness level, and power consumption if supported.
Output is formatted as a table by default. Use -o json or -o yaml for
structured output suitable for scripting.
Columns: ID, Name, State (ON/OFF), Color (R:G:B), White, Brightness (%), Power
