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.

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.
