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.

Select a device, then either stream the microphone or choose an MP3 file. The page decodes audio and pushes 8kHz PCM chunks to that device queue.

Pick one device from the list first.
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.
