Refactor StoreDevice to use spi::flash API

Replace legacy `spi_flash_*` calls in `storedevice.cpp` with the namespaced `spi::flash` and `spi::flash::cmd` interfaces for probe, metadata, read, erase, and write operations. Also updates the startup log line to explicitly label the detected device as SPI flash.
