fix(messages-recv): preserve custom WAMessageKey fields after proto roundtrip

proto.WebMessageInfo.fromObject() rebuilds the key from proto.MessageKey
schema, which only declares remoteJid/fromMe/id/participant. Custom
Baileys extensions (participantAlt, participantUsername, addressingMode)
are silently dropped, so process-message.ts cannot read them downstream
and authorUsername/authorPn are lost on group-participants.update,
groups.update, and group.join-request events that originate from
notifications.

Re-attach msg.key after the roundtrip to preserve the custom fields.
Addresses Codex P2 review comment on PR #382.
