Fix for RGB color override and brightness for EC Type K

[Cipulot]

Description

This fix has 2 changes:

• change of max brightness from 200 to 175
• addition of rgblight_set() in indicator handling

The first is to remain within the 500mA current limit.

The second addresses an issue I encountered when setting static light mode in the RGB effects.
Before the addition, I was tricked into thinking that the code was correct because the behavior was normal in modes like Swirl and similar.
The issue tho was that the bypass of the color set was managed by the effect manager instead of myself, making me believe that the colors for indicators were updated as I called them.
Re reading through docs tho made me realize that this is not the case and I had to add that line to correctly apply the color set.
