[Plan-15] Increment 2: Firmware dispatch

[basmeerman]

Context

Plan 15: MQTT SoC Injection — Increment 2 of 3

Scope

Add dispatch cases in esp32.cpp mqtt_receive_callback() for SoC MQTT commands.

Acceptance Criteria

• MQTT_CMD_INITIAL_SOC → sets InitialSoC, calls RecomputeSoC()
• MQTT_CMD_FULL_SOC → sets FullSoC, calls RecomputeSoC()
• MQTT_CMD_ENERGY_CAPACITY → sets EnergyCapacity, calls RecomputeSoC()
• MQTT_CMD_ENERGY_REQUEST → sets EnergyRequest, calls RecomputeSoC()
• MQTT_CMD_EVCCID → strncpy to EVCCID
• ESP32 and CH32 builds pass

Dependencies

Increment 1

Files

• Modify: src/esp32.cpp
