Two issues caused the timezone step to fail on first run:
1. Sudo credential cache (default 15 min) can expire during the long
apt install step before configure_timezone runs. Added `sudo -v`
immediately after the install confirmation prompt to prime the cache
as late as possible, just before the first long-running step.
2. `sudo timedatectl set-timezone` can fail with "Access denied" if
polkit/D-Bus is not yet fully ready in the install environment.
Added a direct fallback (ln -sf localtime + tee /etc/timezone)
that bypasses D-Bus entirely.

On Ubuntu 22.04+, useradd creates home directories with 750 permissions,
so the non-root user running the script cannot traverse /home/kiosk to
check file existence with [[ -s ]]. sudo tee (running as root) writes the
files successfully, but the bash test always returned false, falsely
reporting all extractions as failed.
Switch to `sudo test -s` to match the pattern already used elsewhere in
the script (line ~10320) when checking files under /home/kiosk.
