test(voice): disable E2EE entirely — check if EC sends plaintext vs encrypted

Browse Source 
If VAD triggers → EC audio reaches pipeline without decryption (plaintext or format issue).
If VAD silent → E2EE encryption on EC side but key/format mismatch on our side.
Note: bot greeting will be unencrypted so EC may not hear it.
