Two more runtime root file-primitive subsystems moved behind self-
validating root-owned helpers so the scoped sudoers needn't grant blanket
sudo sed/tee/cp on /etc (which is root-equivalent — sudo arg wildcards
match across '/', so even path-scoped entries are bypassable):
- scripts/system/libreportal-dns: {clear|add <ip>} — edits /etc/resolv.conf
only, validates the IP argument
- scripts/system/libreportal-ssh-access: authorized_keys + sshd
PasswordAuthentication management, with the lockout guards moved INTO the
helper (the trust boundary) so a compromised manager can't bypass them
- run_privileged: _runRootHelper dispatcher + runResolv / runSshAccess
(runOwnership now uses it too)
- init.sh: initRootHelpers installs all three helpers root:root 0755 with
the manager name baked in
- setup_dns -> runResolv (+ ping de-sudo'd, works unprivileged); host_access
+ webui_ssh_access -> runSshAccess

app_generate operates on the manager-owned install template -> runInstallOp
(cp/mv/sed); drop sudo on the interactive editor. localDnsApplyPihole edits
containers/pihole/.../custom.list (docker-install-owned) -> read via runFileOp,
build in a manager /tmp scratch, write back via runFileWrite.

Give dockerCommandRunInstallUser an --argv mode that execs arguments
verbatim (sudo -u <user> env ... "$@") instead of bash -c "$*", and
point runFileOp at it. The old $*+bash -c re-parse silently mangled
backslashes/quotes in args — e.g. sed scripts (\1, \( become 1, ( ) and
the sqlite3 .backup arg — so rootless data-plane ops with regex were
broken. Verified: the WG_DEFAULT_DNS sed now applies correctly as the
install user. All existing runFileOp callers pass plain commands, so the
switch is safe (and fixes the latent sqlite3 case).
Convert scripts/network/dns/setup_dns.sh: /etc/resolv.conf edits and
ping -> runSystem; the WG_DEFAULT_DNS compose-file sed -> runFileOp.
Byte-identical in rooted; correct in rootless.

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.
