feat: implement all 6 fork parity behaviors

Browse source 
- ZMK_RGB_EFFECT_PERSISTENT flag: layer effect survives RGB toggle
- on_idle callback: wake re-renders layer, sleep turns off without
  clearing layer_effect_active
- is_active callback: ext power stays on for layer RGB
- Wakeup filtering: battery events (wakeup=false) don't wake sleeping
  RGB, layer changes (wakeup=true) do
- Layer filtering: only refresh when changed layer matches active top
  layer, skip unnecessary re-renders
- Fade delay: calls zmk_rgb_set_tick_delay() with per-layer DT
  fade-delay prop after rendering static pixels

Requires: zmk fork rgb-modular-v1.1 branch
