boot.isContainer disables services.udev, which NetworkManager depends on
to enumerate devices — this left NM unable to reliably manage the
container veth, breaking DHCP-hostname registration in Pi-hole. It also
defaulted networking.useHostResolvConf to true, which assumes a
systemd-nspawn-style resolv.conf bind-mount that real Proxmox LXC doesn't
provide (nixpkgs' own proxmox-lxc.nix module forces this false for the
same reason). Also guard the networkmanager extraGroups membership in the
minimal/gui build-types, since that group only exists when NM is enabled.

Generates all nixosConfigurations from mkTarget(platform, buildType,
hostPath) instead of hand-written per-host blocks, so adding a new
platform or build type is a one-line addition. Per-machine identity
(hostname, hostId, secrets, stateVersion) moves into hosts/<name>/host.nix;
platform-specific config (hardware, boot, networking) into
modules/platforms/*.nix; build-type config (minimal/server/docker/gui/
nix-cache/pxe-boot) into modules/build-types/*.nix.
Old flat targets (nixos, docker, server, nix-cache, nix-minimal, pxe-boot)
are replaced by the 17-target <platform>-<buildtype> matrix; each new
target was verified to evaluate before its old counterpart was removed.
CI workflows and docs/aliases now discover hosts dynamically via
nixosConfigurations attrNames and /etc/flake-target instead of hardcoded
lists, so they can't drift from flake.nix again.
