mhx b1562ef2b9 ✅ cidr: cover the invariant the range matching rests on ...

The helpers were tested in isolation but nothing tied them together, and
what actually has to hold is that the key SetCIDR writes for a decision is
one of the keys GetCIDR looks up for an IP that decision covers. A
formatting change on either side would have silently stopped every range
decision from matching with all tests green.

TestCIDRKeys_MatchNormalizeCIDR pins that both ways, including the cases
worth being explicit about: a decision that is not on a network address,
IPv4 mapped clients against an IPv4 range, and that the two families do not
mix. Dropping the mask in cidrKey fails 9 of its cases.

Also covers CIDRLookupKeys against CIDRKeys length by length, the IPv6 side
of the network address test, and CIDRPrefixLen.
