truma_inetbox: fix compile on ESP32 Arduino

- Add missing member fields for stream+master config in LinBusListener
- Expose write_lin_master_frame_ as protected
- Make LinBusLog use <cstdint> and uint8_t
- Add <queue> + declarations for lin_reset_device/has_update_to_submit in TrumaiNetBoxApp.h
- Arduino: fix UART calls and add helper prototypes in LinBusListener_esp32_arduino.cpp

Tested: esphome compile tests/test.esp32_ard.yaml (build OK).
