nixnuc: plain postfix relay to hetznix01 via Tailscale

Browse source 
A minimal Postfix instance on nixnuc accepts local mail submissions from
services and relays everything to hetznix01.atlas-snares.ts.net on port 25
via the Tailscale tunnel. Root and gene aliases forward to @technicalissues.us.
The simple-nixos-mailserver module (postfix + dovecot stack) is removed since
nixnuc does not receive external mail. The nginx server alias for
mail.home.technicalissues.us is dropped. The private-flake input is pinned to
the nixnuc-postfix-relay branch to pick up the matching relay trust change on
hetznix01.
