feat(inbox): preserve channel logo with voice badge in inbox/sidebar

Inboxes with voice enabled were showing a generic phone icon in the
inbox list and sidebar, hiding the underlying channel (e.g. WhatsApp).
Keep the native channel logo and overlay an audio-waveform badge when
voice is enabled. The native Twilio Voice inbox (TwilioSms with no
WhatsApp medium) still resolves to the phone icon.
