@*
    #145 — Driver-instance options panel for the Modbus driver. Surfaces every option group
    added by #136-#144 so users can configure the driver via the UI rather than hand-editing
    DriverConfig JSON. Bound to a ModbusOptionsViewModel; the parent page round-trips that
    model to the DriverConfig.json column on save.
