cottongin 7805c5359e refactor: use EPD-exact bgr888 palette with bulk pushImage ...

Replace the PALETTE_565 + writePixel loop with a bgr888_t palette whose
values exactly match Panel_ED2208's internal epd_palette, pushed via a
single pushImage() call.

Benefits:
- Eliminates ~240K individual writePixel calls per frame
- Zero-distance palette values guarantee correct color mapping
- Removes lossy RGB565 intermediate encoding
- Remove unused paletteToColor565() helper

Also adds informational comment to triggerRefresh() noting that
Panel_ED2208::_exec_transfer always sends the full 400x600 frame.
