    fix: SCALE_IN action not honoring specified node count

    The SCALE_IN action in the lb_policy module was removing only
    one node from the load balancer, regardless of the specified
    count when the count was greater than 1. This was due to a
    hard-coded count of 1 in the _get_delete_candidates function.

    The root cause has been addressed by updating the
    _get_delete_candidates function to dynamically handle the count
    for SCALE_IN. The count is now retrieved from the action inputs,
    and if not specified or invalid, it defaults to 1.
