- Integrate the Zephyr Settings subsystem to persist Modbus parameters. - Use NVS (Non-Volatile Storage) as the backend with a dedicated flash partition. - Modbus baudrate and slave ID are now loaded at startup. - Changes made via the shell are saved to flash and survive a reboot. - Add a 'reset' command to the shell for easier testing. - Fix all compiler and devicetree warnings for a clean build.
