Follow-up to the backup-refresh throttle/dedupe, cutting the cost of the
remote pulls that do still happen.
* restic stats now runs in --mode raw-data (restic_check.sh). The default
restore-size mode walks every snapshot's tree to sum logical file sizes —
the slowest restic op — just to fill a size readout. raw-data reads the
index only and reports the repository's actual deduplicated on-disk size,
which is exactly what the dashboard already labels "deduplicated,
encrypted". raw-data omits total_file_count, so the per-location card now
shows that location's snapshot count (already loaded client-side, and more
useful for a backup repo) instead of a file count.
* engineLocationStats now shares the same per-refresh memoiser as
engineSnapshotsJson (engine_dispatch.sh). Both the locations and dashboard
generators call it per location, so repo stats went from two restic calls
per location per refresh to one. Factored the cache into _engineCachedPull.
* SSH connection reuse for SFTP locations (backup_ssh.sh): ControlMaster=auto
with a self-reaping ControlPersist master, so the several restic
subprocesses a refresh/backup spawns against one location share a single
authenticated connection instead of a fresh handshake each — the dominant
per-call cost on a high-latency link. Toggle via CFG_BACKUP_SSH_MULTIPLEX.

The borg/restic/kopia engines all dropped to the dedicated backup user
via scattered 'sudo -E -u $docker_install_user'. Centralize that into a
single runBackupOp helper so the backup subsystem has one audit point and
the scoped sudoers needs only the (dockerinstall) drop rule.
Also:
- owncloud config heredoc tees -> runSystem (container-UID file)
- webui_display_logins: fix the broken 'command -v sudo sqlite3' guard
to 'command -v sqlite3' (body already runs sqlite3 via runInstallOp)
