chore: Update monitor service and instance controller

Refactored the instance controller and monitor service to improve the connection handling and management of WhatsApp instances.

- Modified the instance controller to close the WebSocket connection and restart the instance instead of reloading it.
- Updated the monitor service to remove the instance from the `waInstances` object and emit an event to clean up and remove the instance data.
- Fixed an issue where the instance was not being removed from the `waInstances` object.
