Adds per-zone configuration to group rate limit keys by network prefix, allowing IPv6 addresses within the same subnet (e.g. /64) to share a single rate limit bucket. This prevents abuse from clients cycling through random addresses within an IPv6 prefix. Each address family has its own setting (ipv4_prefix, ipv6_prefix) so they can be configured independently. When unset (0), addresses are treated individually as before — no change in default behavior. Closes mholt#23 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
