ESP32 Voice Bridge

ESP32 logs in with DEVICE_ID after Wi-Fi is ready. A phone browser can then pick one device and stream microphone audio to the MAX98357A speaker path.

Put the phone and ESP32 on the same Wi-Fi network. If the page opens but the microphone cannot start, HTTPS is the first thing to check.
