cd4fd55a6d feat(desudo): helper-ize backup-engine + app-config installs; retire standalone WireGuard
Bring the remaining deferred subsystems under the scoped sudoers, and drop
the one that's redundant.

Backup engines + app configs -> root-owned helpers (same pattern as
ownership/dns/ssh/socket/svc):
- scripts/system/libreportal-bininstall: install <restic|kopia> — does the
  whole pkg-manager/signed-download install itself for a fixed, validated
  engine name (no blanket sudo apt-get/install). restic_install/kopia_install
  call it.
- scripts/system/libreportal-appcfg: {adguard-auth <user> <bcrypt>|
  crowdsec-priority|owncloud-config <public> <host> <ip> <public_ip>} —
  faithful ports of the AdGuard yaml / CrowdSec bouncer / ownCloud config.php
  rewrites, fixed paths + validated args. adguard_auth/crowdsec_fix_priority/
  owncloud_setup_config call it.
- run_privileged: runBinInstall / runAppCfg; init.sh installs + allowlists both.

Retire standalone (host-level) WireGuard — it's a duplicate of the
containerized containers/wireguard app (+ headscale mesh), its slirp4netns
speed rationale is largely moot with a better rootless net backend / typical
WAN-bound throughput, and it was the heaviest host-root subsystem (apt +
sysctl + iptables + /etc/wireguard), the worst fit for the rootless/
least-privilege direction:
- moved scripts/wireguard/ + manage_wireguard.sh + check_wireguard.sh to
  scripts/unused/; dropped the install-path call, the Tools menu 'w' entry,
  and the requirement check; removed the half-built libreportal-wg helper.
- generate_arrays.sh now also skips system/ (root-owned helpers, never
  sourced); arrays regenerated (files_wireguard.sh pruned).

9af2465ffe feat(desudo): socket + systemd-svc helpers; route traefik/db chowns + svc
Move the last runtime-critical root file-primitive subsystems behind
root-owned helpers so the type switcher + task service work under a scoped
sudoers:

- scripts/system/libreportal-socket: {rootless|rooted} {on|off} chmod of
  the docker sockets (paths computed from config, not caller-supplied;
  exit 3 = absent so the *_found flags come from its exit code)
- scripts/system/libreportal-svc: GENERATES + installs the systemd unit
  from config (mode/uid/baked manager) — never accepts unit content from
  the caller (arbitrary unit = root). Idempotent install/enable/restart.
- ownership helper: add db-own + app-file <app> <relpath> actions
- run_privileged: runSocket / runSvc
- set_socket_permissions -> runSocket; webui_install_systemd -> runSvc
  (+ crontab cleanup runs as the manager directly, no sudo -u self)
- before_start: db chown -> runOwnership db-own; traefik cert/yml ->
  runOwnership app-file (retires updateFileOwnership/changeRootOwnedFile)
- init.sh installs all five helpers

d17e8814d0 feat(desudo): root-owned DNS + host-SSH-access helpers
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

46622cd2f9 feat(desudo): root-owned ownership helper (no blanket sudo chown needed)
Under Model A the runtime runs as the manager, so establishing the
/docker ownership model needs root. Granting the manager a blanket
'sudo chown'/'sudo chmod' in the scoped sudoers would be root-equivalent
(chown /etc/sudoers, ...). Introduce a self-contained, root-owned helper
that performs only a FIXED set of reconciles on FIXED LibrePortal paths,
with owners derived from config + a baked manager name (never the caller)
and a strictly-validated app-name argument.

- scripts/system/libreportal-ownership: the helper (actions: reconcile,
  traversal, containers-top, app-perms, webui, taskdir, app-data-nobody)
- run_privileged: runOwnership wrapper (sudo the installed helper; run the
  bundled copy directly when already root mid-install)
- init.sh: installOwnershipHelper bakes the manager name and installs it
  root:root 0755 to /usr/local/sbin (manager can't modify it)
- libreportal_folders/app_folder/app_update_specifics/task processor:
  delegate the ownership chowns to runOwnership instead of runSystem chown

This removes chown/chmod-on-/docker from the runtime sudo surface, a
prerequisite for a non-root-equivalent scoped sudoers.
