Adds storage support for WhatsApp business-scoped user identifiers received from Meta Cloud API and Twilio WhatsApp webhooks. The change keeps existing phone-based behavior intact, stores BSUID and parent BSUID values as additional `contact_inboxes.source_id` rows for the same contact, and allows BSUID-only inbound messages to create contacts, conversations, and messages without requiring a phone number. Related: https://github.com/chatwoot/chatwoot/issues/13837 **What changed** - Extended WhatsApp source ID validation to accept regular BSUID and parent BSUID formats. - For Meta Cloud API, stores phone, `user_id`, and `parent_user_id` identifiers as contact inbox source IDs when they are present. - For Twilio WhatsApp, stores phone, `ExternalUserId`, and `ParentExternalUserId` identifiers as contact inbox source IDs while preserving the existing `whatsapp:` Twilio source ID shape. - Supports BSUID-only inbound messages by creating a contact, contact inbox, conversation, and message even when the phone number is missing. - Links phone-first and later BSUID-only messages to the same contact when the first payload contains both phone and BSUID. - Stores WhatsApp usernames in contact `additional_attributes`, matching existing social channel patterns. - Keeps existing phone-based outbound and new-conversation behavior unchanged for this milestone. **How to test** 1. Send a Meta Cloud webhook payload with both `wa_id` and `user_id`. 2. Verify Chatwoot creates or finds the phone `contact_inbox` and also creates a BSUID `contact_inbox` for the same contact. 3. Send a later Meta Cloud payload for the same user with only `user_id` / `from_user_id`. 4. Verify Chatwoot finds the BSUID `contact_inbox` and creates the inbound message without requiring a phone number. 5. Send a Twilio WhatsApp webhook with `From: whatsapp:+E164`, `ExternalUserId`, and optionally `ParentExternalUserId`. 6. Verify Chatwoot stores the Twilio phone and BSUID identifiers as `whatsapp:`-prefixed source IDs for the same contact. 7. Send a Twilio WhatsApp webhook where `From` is `whatsapp:<BSUID>` and there is no phone number. 8. Verify Chatwoot creates the contact, contact inbox, conversation, and message without a phone number. --------- Co-authored-by: Muhsin <12408980+muhsin-k@users.noreply.github.com>
