librelad e5f6f4c371 feat(dns): split-horizon local DNS for app subdomains
setupLocalDnsRewrites points every configured domain at the server's LAN IP
inside the self-hosted resolver, so app subdomains resolve locally and hit
Traefik directly (valid certs, no router hairpin). AdGuard gets a wildcard
rewrite per domain via its REST API; Pi-hole gets per-host A records in the
supported, mounted custom.list (no wildcard support there). Safe by
construction: idempotent, guarded by installed-checks, cannot corrupt the
resolver. Hooked into the Apply-DNS actions and resolver install. Also drops
the dead HOST_NAME read from the setupDNSIP stub.

NOTE: needs a live smoke-test — the AdGuard API call and Pi-hole reload
can't be exercised without the running containers.
