Subject: [PATCH] fix: add tag propagation to autoscaling group instances

Add Name tag and dynamic tag blocks to the sensor autoscaling group to
ensure tags are properly propagated to EC2 instances at launch. This
enables better resource identification and organization of sensor
instances within the ASG.
