temphummon dev d9bac7cf28 Document icon-probe results; keep iconfinder bitprobe as artifact 
Probed remaining frame bytes for Bluetooth/power icons on a blank panel:
- found cross-wired glyph dots (byte0 bit7, byte4 bit7) and an I2C timeout
  (byte8 bit4), but no standalone icon bits
- waveshare reference does not drive these icons; likely multi-bit or
  unpopulated on the glass (cosmetic, deprioritized)
- restore temphummon.c as the active firmware build in CMakeLists
