WhatsApp coexistence replies can carry a BSUID-scoped `context.id` even
when Chatwoot stored the original message with a phone-scoped WAMID.
Although both identifiers refer to the same message, their complete
values differ, so incoming replies retained the external reference but
did not populate the internal `in_reply_to` relationship. Agents
consequently saw the reply text without the quoted-message preview.
This resolves the original message within the selected conversation and
stores the internal reply relationship. Exact WAMID matches remain the
primary path; scoped identifiers fall back to the unique decoded message
token.
Fixed
https://linear.app/chatwoot/issue/CW-7663/whatsapp-quoted-replies-are-not-linked-across-scoped-wamids
and https://github.com/chatwoot/chatwoot/issues/14953
## How to reproduce
1. Use a WhatsApp Cloud inbox with coexistence enabled.
2. Send a message whose source ID is stored using the phone-scoped
WAMID.
3. Reply to it from WhatsApp when the webhook carries a BSUID-scoped
`context.id` for the same message.
4. Before this change, the incoming message appears without its
quoted-message preview.
5. After this change, the reply references and displays the original
message.
## What changed
- Resolve incoming reply context IDs against messages in the selected
conversation.
- Keep exact source-ID matching as the first lookup path.
- Decode scoped WAMIDs and match only a unique 20- or 32-character
message token.
- Populate `content_attributes.in_reply_to` while preserving
`in_reply_to_external_id`.
- Leave malformed, unmatched, or ambiguous identifiers unlinked.
## How to test
1. Open a WhatsApp Cloud conversation and send a message to the contact.
2. Reply to that message from WhatsApp through a coexistence identity.
3. Confirm the incoming message displays the original message as a
quoted preview.
4. Confirm ordinary exact-ID replies continue to resolve.
5. Confirm an unknown or malformed context ID does not attach to another
message.
## Things to know
Meta documents `context.id` as the replied-to message identifier, but
does not document the internal WAMID encoding or the phone-versus-BSUID
scope transformation. The fallback is therefore limited to the selected
conversation and succeeds only when one stored message has the decoded
token.
