feat(screen): stream framebuffer to the client as FromRadio display_frame chunks

Browse Source 
ScreenMirror snapshots the 1bpp OLEDDisplay buffer after each committed
frame (updateUiFrame), diffing against the last sent snapshot so only
changed frames stream. Armed via the new AdminMessage set_display_mirror
(continuous) / get_display_frame_request (one-shot); chunks drain through
PhoneAPI's STATE_SEND_PACKETS chain like XModem, so BLE, serial and TCP
clients all receive them. The lockdown path mirrors the LOCKED frame,
preserving display redaction. Excludable with MESHTASTIC_EXCLUDE_SCREEN_MIRROR.

Bumps the protobufs submodule to the DisplayFrame PoC commit and
regenerates nanopb sources (FromRadio_size stays 510 <= 512).
