fix(whatsapp): resolve LID sender IDs to phone numbers in bridge message payload

WhatsApp has migrated to Linked Identity Device (LID) format for user
IDs (e.g. 244645917392975@lid instead of 18505551234@s.whatsapp.net).

The bridge already resolves LIDs to phone numbers for its own allowlist
check via buildLidMap(), but the senderId field in the message payload
sent to the gateway still contained the raw LID. This caused the
gateway's WHATSAPP_ALLOWED_USERS check to reject all messages as
unauthorized, since the LID numbers don't match the phone numbers in
the allowlist.

Fix: resolve LID → phone in the senderId, senderName, and chatName
fields of the event payload before sending to the gateway, using the
existing lidToPhone mapping.
