Marc Childress ee81b3b7ec config: clarify STM32F401 flash instructions for Ender 3 S1 
- Warn that 64KiB bootloader offset is required; using 32KiB places
  firmware at wrong address causing the MCU to crash-loop while
  displaying the Creality splash screen (frozen starfield), which can
  be mistaken for Klipper running successfully
- Clarify that STM32F4_UPDATE folder is required (not root directory)
  for STM32F401 boards
- Note that the bootloader flashes all .bin files in STM32F4_UPDATE
  on every boot, so the SD card should be removed after flashing
- Clarify that the firmware filename must be unique (not previously
  flashed) to ensure the bootloader applies the update
