fix(install): establish container layer in root phase (real fix for scan noise)

Reverts the 2>/dev/null band-aids and fixes the root cause. The
manager-run install boot scans app configs under /docker/containers AS
the container user (runFileOp). But init.sh's initFolders creates that
dir manager-owned, and the handover to the container user happened later
(start_preinstall), AFTER the boot scans — so the scans ran as the
container user against a dir it didn't own yet: "find:
'/docker/containers/': Permission denied" (cosmetic; the dir is empty
that early, but it's the wrong ownership at the wrong time).

Add initContainerLayer() to init.sh's root phase (after initGIT +
initUpdateConfigs, before the manager-run handoff): rootless-only, it
creates the docker-install user if missing and chowns /docker/containers
to it (751). The later rootless setup is now idempotent — it finds the
user existing and just (re)asserts its password + daemon config (moved
updateDockerInstallPassword out of the create-only branch). Rooted is
unaffected (containers stay manager-owned, which the manager reads).

Result: by the time the boot scans run, /docker/containers is owned by
the user doing the scanning — no permission error, nothing suppressed.
