Group service modules by category (media, network, vpn, identity,
dev, desktop) to make the growing services/ dir easier to navigate.
containers.nix stays at the top level since it's a shared backend,
not a single-category service.

Shorten verbose multi-paragraph comments to essentials, and drop a
stale claim in common.nix that jupiter kept its own copy of the base
config (it now imports common.nix directly).

- services/pihole.nix: official pihole/pihole:2026.07.2 via podman, host net,
caps NET_ADMIN/NET_RAW/SYS_NICE/CHOWN; FTLCONF_* env config (upstream unbound,
DHCP 50-200, static lease jupiter, .sol domain, local records)
- unbound: resolveLocalQueries=false (was hijacking resolv.conf to :53 -> boot
DNS deadlock; the real root cause of the earlier failures too)
- password via sops FTLCONF env file; /var/lib/pihole created via tmpfiles
- VM-verified: mercury.sol/jupiter.sol/external all resolve, 0 restarts
pihole.toml is nix-managed read-only so 'pihole setpassword' fails. pihole-FTL
reads FTLCONF_* env vars (override the toml) — render an env file from the sops
secret pihole_webpassword and feed it via EnvironmentFile. Password stays out of
repo/store. VERIFIED in VM: FTLCONF_webserver_api_password -> API login works.
- 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)
- nixosConfigurations.mercury: aarch64, sd-image-aarch64, imports common.nix
- static net placeholders (CHANGE-ME), hostname mercury
- DNS service left undecided: commented pihole (services.pihole-ftl) + adguardhome
- no sops yet (add with the service if it needs a secret)
