fix(certificates): temporarily distrust emSign ECC Root CA - G3

Eight eMudhra intermediates chaining to this root were generated with trivially recoverable private keys (Mozilla bug 2083449), so anyone can mint certificates that non-browser clients using the system bundle will accept. Browsers already block them; the system bundle does not until cacert 3.131.1 (nixpkgs f903b88), which has not reached nixos-unstable yet. Drop this once the flake lock includes that commit.

aaronandClaude Opus 5.5	fb3e2864d6	fix(tailscale): open Tailscale's WireGuard port in the firewall services.tailscale.openFirewall defaults to false while the NixOS firewall is enabled, so argon, krypton and neon dropped unsolicited inbound 41641/udp. Direct connections then only succeed if the other peer accepts inbound; between two of these hosts (or a host and a phone) traffic can fall back to a DERP relay.
