uploadMedia() returns the full API response array, not just the id string.
chat_upload_media.php was passing the whole array as $mediaId, producing
{"image": {"id": {"id": "...", "messaging_product": "..."}}} which
violated WhatsApp JSON schema for the media id field.
Also remap audio/webm (browser MediaRecorder default) to audio/ogg at
upload time since WhatsApp's media API rejects webm but accepts ogg/opus.
