fix(alb): create_before_destroy on target group + depends_on on listener

When the ALB port changes (simple 80 → complex 443), terraform tries to replace the target group while the listener still references it, causing ResourceInUse. Added lifecycle { create_before_destroy = true } to the target group and depends_on = [aws_lb_target_group.this] to the listener so the new target group is created before the old one is destroyed. ---ci--- project: acdl phase: P59 milestone: v1.11 status: execute ---/ci---
