Johnathan Corgan eaba693b18 packaging: bring systemd tarball to feature parity with .deb / AUR
The generic systemd install tarball is the catch-all install path
for systemd Linux distros that don't have a per-format package
(Fedora, RHEL/CentOS, openSUSE, Alpine, etc.). It had drifted
behind the .deb and AUR packages and was missing fips-gateway, the
mesh-interface firewall baseline, and the multi-backend DNS helper
in the shipped tarball. Bring it to parity:

- New `packaging/systemd/fips-gateway.service` (clone of the .deb
  unit; ExecStart pointed at `/usr/local/bin/fips-gateway`). Not
  enabled at install time; operator opt-in.
- New `packaging/systemd/fips-firewall.service` (clone of the .deb
  unit; nft path unchanged at `/usr/sbin/nft`). Not enabled at
  install time; operator opt-in.
- `build-tarball.sh` now bundles the `fips-gateway` binary, the two
  new units, the `fips.nft` baseline conffile, and the
  `fips-dns-setup` / `fips-dns-teardown` multi-backend helpers from
  `packaging/common/`.
- `install.sh` now installs `fips-gateway` to `/usr/local/bin/`,
  installs both new units to `/etc/systemd/system/` (without
  enabling them), preserves `/etc/fips/fips.nft` on upgrade like
  `fips.yaml`, and creates the `/etc/fips/fips.d/` operator drop-in
  directory. Post-install messaging mentions both opt-in services.
- `uninstall.sh` stops and disables the optional services in
  dependency order (firewall, gateway, dns, daemon), removes the
  new unit files, and removes the gateway binary. `--purge` already
  handles `/etc/fips/` removal which covers `fips.nft` and
  `fips.d/`.
- `README.install.md` documents all of the above: expanded
  "What Gets Installed" table, new sections covering the firewall
  baseline and the LAN gateway, refreshed DNS section reflecting
  the multi-backend setup helper (systemd dns-delegate /
  systemd-resolved drop-in / per-link resolvectl / dnsmasq /
  NetworkManager-dnsmasq), and updated Service Management.

Also fixes a latent packaging bug: `install.sh` previously
referenced `${SCRIPT_DIR}/../common/fips-dns-setup`, a path that
exists only in the source-repo layout and not in the extracted
tarball. The script now resolves the helper from the staging
directory first (the tarball case), falling back to the source-repo
relative path. Bug latent since the multi-backend DNS helpers
landed.

CHANGELOG `[Unreleased]` documents the parity bump under Changed
and the path-resolution fix under Fixed.

Closes the longest-standing parity gap for non-Debian / non-Arch
systemd Linux distros installing from the release-distribution
tarball.
