Self-provisioning, visible-tile-only updates, cleanup dead async code

Browse source 
T-Watch self-provisions EEPROM on first boot (blank flash recovery).
Writes product/model/hwrev so the firmware can initialize without
rnodeconf. Full cryptographic provisioning still requires rnodeconf
with T-Watch product code support (not yet upstream).

GUI updates only format labels for the currently visible tile —
GPS float formatting (%.6f) skipped when GPS screen not shown,
radio/battery labels skipped when not on those screens.

Removed dead async DMA code from CO5300.h (spi_device_queue_trans
doesn't work on ESP32-S3 SPI3 with this driver version).

Removed SPI mutex from sx126x.cpp (unnecessary with exclusive
SD/LoRa mode switching). SharedSPI.h retained for IMULogger/Gui
SD card access coordination.
