fix(ipam): clean up NIC and MAC map entries when releasing shared IP

When multiple pods share an IP (e.g. VM live migration), releaseAddr()
only updated V4IPToPod/V6IPToPod but left stale entries in V4NicToIP,
V6NicToIP, NicToMac, and MacToPod for the released NIC. This caused
memory leaks and MAC address exhaustion in long-running environments
with frequent VM migrations.

Also fix CIDR change path to clean up PodToNicList for NICs whose IPs
fall outside the new range.
