- Set board_build.arduino.memory_type = qio_opi. The RAK3112 (ESP32-S3R8) has 8MB octal PSRAM; the esp32-s3-devkitc-1 default (qio_qspi) failed with "PSRAM ID read error ... wrong PSRAM line mode", so BOARD_HAS_PSRAM builds ran without PSRAM (MQTT limited to 2 slots, TLS on internal heap). - Remove PIN_ADC_CTRL (GPIO36) handling copied from Heltec V3. The RAK3112 has no ADC enable pin and GPIO33-37 are used by the octal PSRAM. - Read VBAT with calibrated analogReadMilliVolts() and the WisBlock base board divider (1M/1.5M, empirical x1.73 as in Meshtastic's RAK4631). - Sensor env: drop ENV_PIN_SDA/SCL=33/34 (Heltec V3 values, PSRAM pins). - Exclude MQTTMessageBuilder/JWTHelper from non-MQTT envs so they build without the MQTT-only libraries (Timezone.h not found). Tested on RAK3112 + RAK19007: PSRAM found (8MB), 5 MQTT slots, both dutchmeshcore collectors connected, battery reads 4139 mV on a full LiPo.

Samenvatting
De RAK3112-variant was grotendeels gekopieerd uit de Heltec V3-variant. Daardoor werkte de PSRAM niet en klopte de batterijmeting niet. Deze PR past alleen
variants/rak3112/aan.Wijzigingen
board_build.arduino.memory_type = qio_opi). De RAK3112 (ESP32-S3R8) heeft 8 MB octal PSRAM. Hetesp32-s3-devkitc-1-board gaat uit van quad PSRAM (qio_qspi), waardoor de boot faalde metPSRAM ID read error ... wrong PSRAM line mode. Builds metBOARD_HAS_PSRAMdraaiden dus zonder PSRAM: maximaal 2 MQTT-slots, en TLS op de interne heap.PIN_ADC_CTRL(GPIO36) verwijderd. Dat is een Heltec-restant. De RAK3112 heeft geen ADC-enable-pin, en GPIO33–37 zijn de lijnen van de octal PSRAM.analogReadMilliVolts()met de spanningsdeler van het WisBlock-baseboard (1M/1,5M, empirisch ×1,73, net als Meshtastic voor de RAK4631 op hetzelfde baseboard). De oude formule kwam van de nRF52 (AREF 3,0 V) en klopt niet voor de ESP32-ADC.ENV_PIN_SDA/SCL=33/34verwijderd (Heltec V3-waarden en PSRAM-pinnen), en de advert-naam "RAK3112 v3 Sensor" is "RAK3112 Sensor" geworden.MQTTMessageBuilder.cppenJWTHelper.cppworden uitgesloten in de basis-[rak3112], en de*_observer_mqtt-envs voegen ze zelf weer toe.

De partitie-indeling is ongewijzigd (8 MB-layout), dus bij een update blijft de opgeslagen config staan. De RAK3112 heeft 16 MB flash, maar overstappen naar
default_16MB.csvzou SPIFFS verplaatsen en de config wissen. Dat laat ik bewust buiten deze PR (omdat die 16MB ook niet nodig is).
