[PATCH 03/16] ui: Replace HOST_BIG_ENDIAN #ifdef with runtime if() check

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Replace compile-time #ifdef with a runtime check to ensure all code
paths are built and tested. This reduces build-time configuration
complexity and improves maintainability.

No functional change intended.
