#23567: fix: add senderE164 and pushName to WhatsApp inbound log line

## Summary Adds `senderE164` and `senderName` (from `msg.pushName`) to the WhatsApp inbound logger output. Both variables were already computed in scope but not included in the log object. ## Changes - Added `senderE164` field to inbound log (line 307) - Added `senderName` field to inbound log (line 308) This is a logging-only change with no impact on control flow or routing logic.
