NixOS's group activation uses plain groupmod, which silently skips the
GID change when SSSD exposes the same GID (50010) via the IPA
docker-access group through NSS. Add an activation script that runs
after the normal 'groups' step and applies groupmod --non-unique so the
local docker group can share GID 50010 with the SSSD-provided IPA group.
If the GID actually changes on a live system the script also restarts
docker.socket + docker.service so the socket is recreated with the new
GID.

Documentation fixes:
- README/AGENTS: rename tailscale-exit-node → tailscale-router, add ha-server
build type and proxmox-ha-server-{1,2} host table rows, add baremetal to
platform list, remove references to non-existent flake-target-refactor-spec.md
and remove-sensetive-info-refactor.md
- docs/auto-installer.md: fix lxc-tailscale-exit-node → lxc-tailscale-router,
add pxe-minimal to the flake outputs list
- variables.nix: fix domainControllerIp comment — IPA is the authoritative DNS
at .253 (Pi-hole is gone), not a forwarding intermediary
Code deduplication:
- Extract duplicate SSH host-key preservation activation scripts from
modules/platforms/lxc.nix and modules/platforms/proxmox.nix into a shared
modules/common/preserve-ssh-host-key.nix; both platforms now import it
- Replace 8-line hand-enumerated NFS export lists in server.nix and ha-server.nix
with a mkNfsExports helper that generates exports from vars.nfsShares — adding
a share to variables.nix now propagates to both exporters automatically
Dead code removal:
- modules/common/configuration.nix: remove leftover NixOS skeleton comments
(hardware-configuration import, grub lines) that were never used
- modules/docker/enable-service.nix: remove commented-out listenOptions and
daemon.settings blocks
- hosts/server/host.nix, hosts/nix-cache/host.nix: remove #DOCKER_HOST comments

Create an IPA group "docker-access" (GID 50010) and pin the local
"docker" group to that GID on all Docker hosts. Any IPA user in the
docker-access group automatically gains docker socket access through
SSSD supplementary-group resolution — no per-host docker.members
entry needed.
Specific changes:
- variables.nix: add dockerAccessGid = 50010
- modules/docker/enable-service.nix: lib.mkForce docker GID to
dockerAccessGid, removing the need to name individual IPA users
- modules/build-types/docker.nix: remove direct wayne docker.members
entry (access now comes from IPA group)
- modules/ipa/client.nix: refactor repeated security.* / systemd.*
top-level keys into merged attribute sets (fixes statix W20); add
security.pam.services.lightdm.makeHomeDir so the GUI login path
also creates the home dir on first login

Zero W20 (repeated attribute keys), W10 (empty { ... }: variadic
pattern, use _: instead), and W04 (a = x.a instead of inherit)
warnings remain anywhere in the tree, and nixpkgs-fmt --check is
clean on all 46 .nix files.
Repeated-key merges go as deep as statix actually flags per file
(e.g. boot.loader.* nested under boot.loader = { ... } once the
outer boot.* merge exposed it as its own repeat) — every merge is a
pure attribute-path restructuring with no value changes, verified by
comparing config.system.build.toplevel.drvPath before/after for a
representative host per changed module plus a full 19-host + 4-package
eval sweep.
One indentation slip caught and fixed during this pass: nesting
modules/installer/common.nix's environment.etc."auto-install.sh".text
under an environment = { ... } block initially normalized the
script's shebang/set line indentation, which actually changes the
rendered file (Nix's '' string dedent treats it as real content, not
cosmetic whitespace) — reproduced the original's exact indentation
and reverified the rendered script is byte-identical to before.
modules/services/zfs/auto-mount-volumes.nix picked up formatting too;
worth noting it isn't imported by anything in this flake at all.
