Load the full hardware config up front rather than only the GPIO section, so display settings can come from the same file. Adds a rotate parameter that falls back to display.rotate in the config when not passed explicitly, and logs the resolved value. Also bumps the dreader-hal submodule to 64c9177 (use partial draw) and adds a direct IT8951 example that bypasses the HAL, for isolating display problems to the driver layer.
