feat(events): add isLatest and progress to messages.set event

- Add extra field to EmitData type for additional payload properties
- Update EventManager and sendDataWebhook to support extra parameters
- Update all event controllers (webhook, rabbitmq, sqs, websocket, pusher, kafka, nats) to include extra fields in payload
- Pass isLatest and progress from Baileys messaging-history.set to messages.set webhook

This allows consumers to know when the history sync is complete (isLatest=true) and track sync progress percentage.
