perf(controller): index IP CRs by subnet for subnet status calculation

calcSubnetStatusIP listed the whole IP store with a label selector on
every subnet status reconcile. Replace it with a bySubnet informer
indexer so each call only walks the IPs of the target subnet, following
the existing IndexPodByNode / IndexEPSByService pattern. The index keys
on Spec.Subnet plus AttachSubnets, matching the subnets enqueued to
updateSubnetStatusQueue on IP add/update/delete.

Behaviour is unchanged: every IP CR is created with both Spec.Subnet and
the dynamic per-subnet label set together, so ByIndex(Spec.Subnet)
returns the same set as the old {subnet.Name: ""} selector.
