dockerCommandRunInstallUser sudo's to the unprivileged docker install user but
inherited the caller's cwd. At install time the caller is root in /root, which
that user can't enter, so cwd-sensitive tools failed — e.g. 'find: Failed to
change directory: /root' / 'Failed to restore initial working directory'
during the app scan (the scan still worked via the absolute start path, but
the errors are noise and could bite other commands). Add env --chdir to the
install user's HOME for both the argv and shell exec paths so every runFileOp
runs from a directory the user can access.

The rooted branch executed the command string as bare $command, which
word-splits without shell interpretation: pipes, redirects, && and quoted
Go templates were passed as literal argv to a single process. Nearly every
caller relies on shell syntax (docker ps | xargs -r ..., cd && docker
compose, --format='{{...}}', > /dev/null), so rooted mode silently
mishandled them — most visibly dockerStartAllApps after its pipe rewrite,
which failed with 'unknown shorthand flag: r'. Run via bash -c like the
rootless path so both modes share identical shell semantics. No caller uses
the sudo type arg.

Maintainer confirmed the intended model: the manager user (libreportal, in the
docker group) owns /docker in BOTH modes and runs things directly; root:root was
always an accident of un-de-sudo'd sudo. Rework the helpers accordingly:
- add runAsManager (run as the manager: plain when already it at runtime, else
sudo -u at install time) so files end up manager-owned, never root-owned.
- runFileOp/runFileWrite: rooted -> runAsManager (was sudo->root); rootless
unchanged (docker install user owns containers/).
- runInstallOp/runInstallWrite: always runAsManager (control plane is manager-
owned in both modes).
- runSystem unchanged (genuine root: apt/systemctl/ufw/sysctl).
All ~40 converted call sites inherit this via the helpers. reconcile's WebUI dir
now -> manager in rooted / docker install user in rootless.

Reinstall test on Debian 12 surfaced three rootless-only breakages (rooted
was byte-identical/fine):
1. pasta blocked by Debian's passt AppArmor profile (DENIED ptrace read ->
can't open container netns -> rootless dockerd never starts). Default
CFG_ROOTLESS_NET back to slirp4netns (reliable); pasta stays selectable
for hosts that relax the profile.
2. de-sudo mis-assigned helpers by owner. /docker management layer (apps DB
chowned to libreportal by install_sqlite, /docker/logs) is MANAGER-owned,
not dockerinstall. Add runInstallWrite; move apps-DB sqlite3 -> runInstallOp
and /docker/logs appends -> runInstallWrite. Revert ownership-SETUP scripts
(libreportal_folders, app_folder) to runSystem — they must run as root to
establish ownership during install. Container files (/docker/containers/<app>)
stay runFileOp.
3. kernel hardening sysctls written to /etc/sysctl/99-custom.conf, which
'sysctl --system' does not read -> never applied. Write them to
/etc/sysctl.d/99-libreportal-hardening.conf instead.

- New runInstallOp helper for manager install-dir/template ops (rooted:
sudo; rootless: run as the current manager user, which owns the tree).
- adguard.sh, traefik.sh: container-config sed -> runFileOp.
- crowdsec.sh: host crowdsec systemctl/apt-get -> runSystem.
- dashy_update_conf.sh: conf-file mkdir/chown/md5sum/tee -> runFileOp/
runFileWrite; docker ps/restart -> dockerCommandRun.
Deferred (cross-owner copy / temp-file across /tmp<->/docker, need rootless
env to bridge correctly): owncloud_setup_config.sh, adguard_auth.sh.

Add -a/--append to runFileWrite so the pervasive /docker/logs log-append
idiom (`… | sudo tee -a $logs_dir/$docker_log_file`) routes through the
mode-aware helper instead of raw sudo.
Convert scripts/config/docker/docker_config_to_container.sh fully: all
ops target /docker app config + logs (data-plane), so md5sum/grep/chmod/
cmp/editor -> runFileOp and the log-appends -> runFileWrite -a.
Byte-identical in rooted.

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.

dockerCommandRunInstallUser ssh'd to <user>@localhost, but nothing set up an
SSH server/keys/authorized_keys, so every rootless setup command (daemon
install, systemctl --user) silently no-op'd. Replace with 'sudo -u <user> env
…' that sets XDG_RUNTIME_DIR / DBUS_SESSION_BUS_ADDRESS / DOCKER_HOST / PATH
explicitly; linger keeps the user systemd + /run/user/<uid> alive so
systemctl --user works. No SSH server, no keys, less attack surface, and
sudo -u to an unprivileged user is not a root escalation.

Single place that decides how a privileged op runs by Docker mode:
- runFileOp / runFileWrite: /docker data-plane ops — rooted uses sudo (identical
to today), rootless runs as the unprivileged install user (no root).
- runSystem: genuine system-admin ops, sudo in both modes, funnelled here so it
can later be confined to a scoped sudoers allowlist.
Call sites converted to these are byte-for-byte unchanged under rooted, so
existing/live boxes can't regress; rootless gets the de-privileged path.
