#10803 refactored main.cpp to key SPI-TFT Screen creation on HAS_SPI_TFT
instead of the per-controller define list. The W10 variant (#10911) was
written before that refactor and crossed it mid-air, so it never defines
HAS_SPI_TFT and develop builds fall through to the I2C-OLED autodetect
branch: no Screen is ever constructed and the display stays dark, while
everything else (radio, GPS, BLE) works.
Verified on a real W10: with the define, the boot log shows TFTDisplay
creation, backlight power-on and the boot screen, and the ST7789 panel
renders the UI again.
