Migrate live secrets to sops-nix (Milestone 2)

Audited the working tree and full git history for committed secrets
(gitleaks + trufflehog + manual grep, see secrets-inventory.md, kept
local/gitignored per the spec). Found: a password hash shared by root
and the nixos user across every host, two live Beszel monitoring
tokens, and a GitHub fine-grained PAT embedded in a home-manager
nix.conf.

Migrates all of them to sops-nix:
- .sops.yaml + secrets/*.yaml, encrypted for admin + the age keys
  derived (via ssh-to-age) from each live host's existing SSH host
  key — no new key material transferred to any machine.
- users.users.{root,nixos}.hashedPasswordFile replaces the inline
  hashedPassword shared by every target.
- The GitHub PAT moves from a home-manager-managed, store-visible
  nix.conf to a sops.templates-rendered file included via nix.conf's
  native !include, system-wide instead of per-user.
- Beszel TOKEN moves from `environment` (store-visible) to
  `environmentFile` (runtime-only via sops.templates); the dead
  commented-out docker token is removed from the tree entirely.

Added a tracked pre-commit hook (gitleaks protect --staged, wired via
core.hooksPath) so a secret can't be committed by accident again, and
documented the sops workflow in README.md.

Structural verification only: all 17 flake targets evaluate, and
`nix build --dry-run --no-link` succeeds for the three currently
deployed hosts. Per CLAUDE.md, actual `nixos-rebuild switch` — the
step that confirms secrets decrypt and services start on a real
machine — is left for manual verification.

Git history still contains the original plaintext secrets; scrubbing
history (Milestone 3) and rotating every credential (Milestone 4) are
separate, deliberately gated steps per remove-sensetive-info-refactor.md.

-# Auto-installer
-
-This flake builds a self-contained NixOS installer environment that can
-install any host exposed by its own `nixosConfigurations`. It was migrated
-from a formerly-separate `nix-auto-installer` repo — everything it did now
-lives here.
-
-The installer provides a small NixOS install environment (ISO/netboot/Proxmox
-LXC) with SSH access, Git support, and an interactive installation script.
-Logging in as any user (root or `nixos`) runs `/etc/auto-install.sh`,
-discovers available hosts from this same flake, lets the operator choose a
-target, applies that host's Disko storage configuration, installs NixOS, and
-reboots.
-
-**This applies to every `nixosConfigurations` target except `lxc-*` hosts —
-see "LXC hosts" immediately below for why those are different.**
-
-## LXC hosts
-
-`lxc-*` targets (`lxc-minimal`, `lxc-nix-cache`, `lxc-server`, `lxc-docker`,
-`lxc-gui`, `lxc-pxe-boot`) are **not** installed via `auto-install.sh` — the
-interactive menu deliberately excludes them. Don't try to select one there;
-`nixos-install` would bind-mount `/` onto `/mnt` (LXC containers have no raw
-disk to partition) and then refuse to touch the filesystem it's currently
-running on — it's designed to protect exactly this case, so it just fails.
-
-`modules/platforms/lxc.nix` imports nixpkgs' own
-`virtualisation/proxmox-lxc.nix` module, which gives every `lxc-*` host a
-`config.system.build.tarball` output — a complete, directly Proxmox-importable
-container image, no install step at all:
-
-```sh
-nix build .#nixosConfigurations.lxc-minimal.config.system.build.tarball
-```
-
-Then, on the Proxmox host, `pct restore` (or the GUI's "Create CT" → upload
-template flow) that tarball directly as a new container. First boot runs
-`boot.postBootCommands` (registers the Nix store DB and system profile) —
-there's no separate activation step to run yourself.
-
-Host keys still need pre-seeding the same way as any other host (see "Host
-keys" below) — the sops-nix activation-vs-first-boot race is identical
-regardless of how the image reaches the machine. `NIXOS_HOST_KEYS_DIR=...
-nix build ... --impure` bakes the matching key into the tarball the same way
-it does for the ISO/PXE installer images.
-
-## Layout
-
-- `modules/installer/common.nix` — shared by every installer target: SSH
-  access, users, the generated `/etc/auto-install.sh` script, and the
-  `programs.bash.loginShellInit` hook that runs it on login.
-- `modules/installer/iso.nix` — ISO/netboot-specific: imports the stock
-  `installation-cd-minimal.nix` module plus `common.nix`. Also used, paired
-  with `netboot-minimal.nix`, to build the PXE netboot variant (see
-  `docs/pxe-boot.md`).
-- `modules/installer/proxmox-lxc.nix` — Proxmox LXC-specific: disables
-  bootloader options (containers don't need one) plus `common.nix`.
-- `modules/installer/host-keys.nix` — optionally bakes pre-generated SSH
-  host keys into the image; see "Host keys" below.
-- `scripts/prepare-host-key.sh` — admin-workstation pre-flight tool, see
-  "Creating a New Machine" below.
-
-Flake outputs:
-
-```nix
-nixosConfigurations.installer     # ISO/netboot installer image
-nixosConfigurations.proxmox-lxc   # Proxmox LXC-based installer image

-```
-
-```sh
-nix build .#iso
-nix build .#lxc
-nix build .#pxe
-nix build .#all
-```
-
-The `pxe` variant is also built automatically as part of the `pxe-boot` host
-itself (`modules/pxe-boot/stage-installer-artifacts.nix`) and served over
-iPXE — see `docs/pxe-boot.md`.
-
-## Host keys
-
-`sops-nix` derives each host's decryption key from its own
-`/etc/ssh/ssh_host_ed25519_key`, generated at **activation** time — before
-systemd would otherwise generate one on first boot. Without pre-seeding this
-key, secrets (including the root/nixos login password) fail to decrypt on a
-genuinely fresh install.
-
-Generated host keys live in `host-keys/` at the repo root (`ssh_host_ed25519_key`
-+ `.pub` pairs per hostname). This directory is **gitignored on purpose** —
-private key material must never be committed — which also means flakes can't
-see it through a normal relative path. `modules/installer/host-keys.nix`
-reads it through `builtins.getEnv`, which Nix silently returns as an empty
-string under normal (non-`--impure`) evaluation, so the module is a no-op —
-safe by default, including in CI — unless explicitly opted into:
-
-```sh
-NIXOS_HOST_KEYS_DIR="$(pwd)/host-keys" nix build .#iso --impure
-```
-
-When built this way, every key currently in `host-keys/` is baked into the
-image at `/etc/host-keys/<hostname>_ssh_host_ed25519_key(.pub)`, and
-`auto-install.sh` automatically installs whichever one matches the flake
-target selected at install time — no manual per-host scp step needed.
-
-**Trade-off, accepted deliberately for this LAN-only setup:** baking keys in
-means every key present in `host-keys/` at build time becomes readable by
-anyone who can reach the built image — including, for the PXE variant, anyone
-who can reach the `pxe-boot` host's unauthenticated HTTP server. This is
-considered acceptable here because `pxe-boot` sits behind LAN-only network
-infrastructure, not the open internet. If that ever changes, reconsider this
-default.
-
-`auto-install.sh` still supports the older manual path as a fallback: if a
-host's key isn't baked in (`/etc/host-keys`), it checks `/root/host-keys`
-next, where you can `scp` a key in after boot, same as before this migration.
-
-## Storage
-
-Disk partitioning is handled by Disko — the installer has no hardcoded
-`parted`/`mkfs`/`mkswap`/`mount` commands. Each host defines its own layout
-via `disko.devices`; a host without one is installed in place via bind-mount
-(this is how every LXC container target works, since they have no raw block
-device to partition).
-
-## Installer process
-
-`/etc/auto-install.sh`:
-
-1. Queries `nixosConfigurations` from this flake over the network (`git+https://<lanDomain>/beatzaplenty/nixos.git`) — this happens at *install* time, not build time, so a generic installer image always sees whatever hosts are currently committed, without needing a rebuild.
-2. Presents them as a menu; confirms the choice.
-3. Skips the `nix-cache` substituter when installing a `nix-cache` host itself (consistent with that host's own runtime config).
-4. Runs `disko --mode destroy,format,mount` if the target has a Disko config, otherwise bind-mounts `/` onto `/mnt`.
-5. Installs the target's SSH host key from `/etc/host-keys` or `/root/host-keys` (see "Host keys" above).
-6. Runs `nixos-install --flake <url>#<choice> --no-root-password`.
-7. Cleans up and reboots.
-
-## Creating a new machine
-
-Do this instead of jumping straight to a plain install whenever the target
-host consumes any sops-nix secret — as of this writing, that's every host
-(`modules/common/configuration.nix` puts the root/nixos password hash and the
-GitHub token behind sops-nix for all of them).
-
-1. **On your admin workstation**, decide the new machine's flake target name
-   (`<platform>-<buildtype>`, e.g. `proxmox-server`) and generate + register
-   its host key:
-
-   ```sh
-   ./scripts/prepare-host-key.sh <hostname>
-   ```
-
-   This generates `host-keys/<hostname>_ssh_host_ed25519_key(.pub)` and
-   prints the `.sops.yaml` snippet to add, which secrets files to
-   re-encrypt it into, and the next steps below.
-
-2. **Edit `.sops.yaml`** with the printed snippet, then re-encrypt every
-   secrets file you added the new host to:
-
-   ```sh
-   nix-shell -p sops --run 'sops updatekeys secrets/common.yaml'
-   ```
-
-3. **Commit and push.** The flake build the installer uses has to see the
-   new recipient before you install, or decryption fails on first boot
-   regardless of the next step.
-
-4. **Build the installer image with keys baked in** (or reuse an already-serving `pxe-boot` host, which does this automatically once redeployed):
-
-   ```sh
-   NIXOS_HOST_KEYS_DIR="$(pwd)/host-keys" nix build .#iso --impure
-   ```
-
-5. **Boot it on the target machine**, log in, select the new host's flake
-   target from the menu, confirm. `auto-install.sh` finds the baked-in key,
-   runs Disko + `nixos-install`, and reboots.
-
-6. **Verify after reboot:**
-
-   ```sh
-   ssh <new-host> ls /run/secrets/
-   ```
-
-   If that's empty or login fails, the host's age key most likely wasn't in
-   `.sops.yaml` (or wasn't re-encrypted into the secrets file it needs) when
-   `nixos-install` ran — fix `.sops.yaml`/`secrets/*.yaml`, push, then re-run
-   `nixos-install --flake .#<hostname> --no-root-password` from a rescue
-   environment against the existing `/mnt`, or just redo the install.
-
-## Safety
-
-This installer is destructive: `disko --mode destroy,format,mount` erases
-any disk defined by the selected host's Disko configuration. Always verify
-the selected host profile and target machine before confirming.

-#
-# This script only touches your admin workstation and this repo's
