feat(screen): stream the TFT color-region palette for color-accurate mirroring

Browse Source 
ScreenMirror captures the color-region table with each snapshot when the
frame signature changes (regions byte-swapped from panel order to logical
RGB565, defaults = White / theme body background) and streams it as
FromRadio.display_palette chunks ahead of frames, with per-client
(signature, region) cursors like the frame drain. Frames reference the
palette via palette_signature; monochrome-only builds send 0 and no
palettes. Also classify USE_TFTDISPLAY/HAS_SPI_TFT panels (T-Deck) as
TFT in DeviceMetadata.display.
