Round-trip test exposed it: during a rooted stint the WebUI (root-in-
container) writes root-owned files into its data dir; back in rootless the
WebUI user (dockerinstall) can't manage them -> container Exited(137).
Since the WebUI is LibrePortal's OWN regenerable 0:0 component, reconcile now
also chowns containers/libreportal to the mode's container owner (root rooted
/ install user rootless). Validated: after this the WebUI returns to HTTP 200.
Third-party app data under containers/ is still untouched (backup/restore).

Mode switches change /docker ownership expectations, but the switcher only
ever fixed the socket — never file ownership — so a rooted<->rootless swap
left the control plane owned for the wrong mode (CLI + de-sudo helpers then
can't access it).
Add reconcileDockerOwnership (single source of truth): swaps ONLY the owner
of LibrePortal's control plane (configs/logs/scripts/DB + /docker top) to the
mode owner (root rooted / manager rootless). It never resets mode bits (only
adds o+x on /docker for traversal and o+r on the DB for the WebUI), and never
touches /docker/containers/** app data, backups/, or ssl/ssh keys. Wired into
both switch branches between container-retag and app-start.
App data is deliberately NOT chowned: container UIDs re-map across modes
(rootless subuid offset), so a chown can't carry e.g. Postgres data across —
that's a backup->switch->restore operation. Switcher now warns to back up
stateful apps before switching and restore after.

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.
