Cherry-picked upstream PR #522 (da4d3b5) with conflict resolution: - Added new lib/hal/ files (HalDisplay, HalGPIO) - Updated GfxRenderer to use HalDisplay, preserving base viewable margins - Adopted PR #522's MappedInputManager lookup table implementation - Updated main.cpp to use HAL while preserving custom Serial initialization - Updated all EInkDisplay::RefreshMode references to HalDisplay::RefreshMode This introduces a Hardware Abstraction Layer for display and GPIO, enabling easier emulation and testing.
