librelad bdd73b4686 harden(desudo): append-capable runFileWrite + convert config-to-container
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.

# Mode-aware privileged operations.
#
# The privilege a file operation needs depends on the Docker mode:
# rooted — app/container files under /docker are root-owned, so ops run via
# sudo. This is byte-for-byte the historical behaviour.
# rootless — those files are owned by the unprivileged Docker install user, so
# ops run AS that user (via `sudo -u`, no root over the data plane).
# Centralising the branch here means each call site is written once and is
# correct in both modes, and rooted installs (incl. live boxes) are unchanged.
# Run a /docker data-plane command — mkdir/chown/rm/cp/mv/find/sqlite3/etc. on
# app or container files.
# rooted -> sudo <cmd>
# rootless -> run <cmd> as the Docker install user (no sudo)
# Note: for stdin-fed writes (e.g. `… | sudo tee file`) use runFileWrite below;
# this helper is for self-contained commands.

# Write stdin to a path with the right privilege (replaces `… | sudo tee path`).

# Usage: some_command | runFileWrite [-a] /path/to/file
