erik 1937d59b2c feat: per-host darman passwords via sops; mercury sops; AdGuard pw via UI
- per-host darman_password (distinct hash) in secrets/{jupiter,vps,mercury}.yaml
  -> hashedPasswordFile; different console password per host (ssh still key-only)
- mercury: dedicated age key (on boot partition post-flash), sops-nix wired
- AdGuard: module has no secret hook + writable config -> mutableSettings=true,
  admin password set via web setup on first boot (never in repo/store)
