Upstream update to v0.31 with fixes to CVE-2025-67603 and CVE-2025-67858

Summary

Foomuuri is a firewall generator for nftables based on the concept of zones.

It is suitable for all systems from personal machines to corporate firewalls,

and supports advanced features such as a rich rule language, IPv4/IPv6 rule

splitting, dynamic DNS lookups, a D-Bus API and FirewallD emulation for

NetworkManager's zone support.

Update Information:

Upstream update to v0.31 with fixes to CVE-2025-67603 and CVE-2025-67858. CVE-2025-67603: Add PolicyKit authorization to D-Bus methods. CVE-2025-67858: Verify interface input parameter on D-Bus methods. Security hardening: Add ProtectSystem=full to all systemd service files. This changes /etc to read-only for all Foomuuri processes. Make sure you don't write any state files there in your startup hook or Foomuuri Monitor event hook. Change umask to 022 when using --fork to fork as a background daemon process. More strict IP address verify for iplist entries.
