Erich Blume a4a30aad44 fix(ringtail): explicitly enable net.ipv4.ip_forward ... After the static IP change, k3s/flannel pod networking broke because ip_forward was 0. NixOS doesn't enable IP forwarding by default — it was previously being set implicitly somewhere in the NM-managed / scripted-DHCP path. With static networking we have to set it ourselves. Verified at runtime via sysctl -w before adding here; pod outbound came back immediately and Tailscale VIP services recovered without any pod restarts.
