## Description
Keeps WhatsApp voice calls in the same thread as the chat when a caller
has adopted a **WhatsApp username** and hidden their phone number.
This makes the inbound-call path BSUID-aware, reusing the same
identifier the messaging pipeline keys on so calls land on the existing
`ContactInbox`/conversation.
