test(ipam): add IPv6 comparison coverage for cmp

Add TestIPCompareIPv6 covering the same-family IPv6 path of the new
comparator: ordering across low/middle/high 16-bit groups, compressed
vs. expanded equality, the multi-byte 00ff<0100 boundary, and the
all-zero / all-ones extremes. Each case also asserts the ordering is
total by checking the reversed operands.
