evan 0bd953d596 fix: turn the backlight on
TFT_eSPI drives the backlight pin only when TFT_BL and TFT_BACKLIGHT_ON are both
defined. Only the first was, so GPIO27 was never even configured as an output: the
panel initialised, took every pixel it was sent and stayed dark.

The emulator cannot catch this. It models the framebuffer, not the lamp, so a board
with no backlight and a board with a perfect one render identically.
