  1. Change RMT idle level to LOW for proper WS281x reset
  2. Increase WS2811 timing T0H from 300ns to 400ns to improve signal stability over long cables
  3. Increase OM_MAX_NUM_CHANNELS from 3000 to 4500 to support up to 4500 pixels for DDP
  4. Enable auto-formatting in LittleFS initialization to fix boot loop on fresh ESP32 firmware
