mhx 4bac63ca83 ✅ cache: cover the CIDR operations and what a lookup costs ...

pkg/cache had tests for Get, Set and Delete but none for their CIDR
counterparts, so the range keyspace was only exercised end to end by the
e2e scenario.

Test_GetCIDR covers hits, the boundaries of a range, IPv6, IPv4 mapped
clients and invalid input. Test_GetCIDR_MostSpecific pins the precedence
between overlapping decisions, which is deliberate behaviour that nothing
was holding in place: a captcha on a /24 is not overruled by a ban on its
/8. Test_DeleteCIDR checks the wider decision survives a narrower one being
removed, and Test_SetCIDR_InvalidIsNotStored that a rejected value stores
nothing at all.

Test_GetCIDR_Reads counts cache reads through an isolated cacheInterface,
so the cost of a lookup is part of the contract: probing every prefix
length again turns it into 34 reads for IPv4 and 130 for IPv6 and fails.
